T. Rowe Price Mid-Cap Value Fund

Certified Semiannual Report (Unaudited)                           June 30, 2004

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

T. Rowe Price Mid-Cap Value Fund, Inc. (the fund) is registered under the
Investment Company Act of 1940 (the 1940 Act) as a diversified, open-end
management investment company. The fund seeks to provide long-term capital
appreciation by investing primarily in mid-size companies that appear to be
undervalued. The fund has three classes of shares: the Mid-Cap Value original
share class, referred to in this report as the Investor Class, offered since
June 28, 1996, Mid-Cap Value--Advisor Class (Advisor Class), offered since
September 30, 2002, and Mid-Cap Value--R Class (R Class), offered since
September 30, 2002. Advisor Class shares are sold only through brokers and other
financial intermediaries, and R Class shares are available to retirement plans
serviced by intermediaries. The Advisor Class and R Class each operate under
separate Board-approved Rule 12b-1 plans, pursuant to which each class
compensates financial intermediaries for distribution, shareholder servicing,
and/or certain administrative services. Each class has exclusive voting rights
on matters related solely to that class, separate voting rights on matters that
relate to all classes, and, in all other respects, the same rights and
obligations as the other classes.

The accompanying financial statements were prepared in accordance with
accounting principles generally accepted in the United States of America, which
require the use of estimates made by fund management.

Valuation
The fund values its investments and computes its net asset value per share at
the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day
that the NYSE is open for business. Equity securities listed or regularly traded
on a securities exchange or in the over-the-counter market are valued at the
last quoted sale price or, for certain markets, the official closing price at
the time the valuations are made, except for OTC Bulletin Board securities,
which are valued at the mean of the latest bid and asked prices. A security that
is listed or traded on more than one exchange is valued at the quotation on the
exchange determined to be the primary market for such security. Listed
securities not traded on a particular day are valued at the mean of the latest
bid and asked prices for domestic securities and the last quoted sale price for
international securities.



Debt securities are generally traded in the over-the-counter market. Securities
with original maturities of one year or more are valued at prices furnished by
dealers who make markets in such securities or by an independent pricing
service, which considers yield or price of bonds of comparable quality, coupon,
maturity, and type, as well as prices quoted by dealers who make markets in such
securities. Securities with original maturities of less than one year are valued
at amortized cost in local currency, which approximates fair value when combined
with accrued interest.

Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation.

Other investments and those for which the above valuation procedures are
inappropriate or are deemed not to reflect fair value are stated at fair value
as determined in good faith by the T. Rowe Price Valuation Committee,
established by the fund's Board of Directors.

Most foreign markets close before the close of trading on the NYSE. If the fund
determines that developments between the close of a foreign market and the close
of the NYSE will, in its judgment, materially affect the value of some or all of
its portfolio securities, which in turn will affect the fund's share price, the
fund will adjust the previous closing prices to reflect the fair value of the
securities as of the close of the NYSE, as determined in good faith by the T.
Rowe Price Valuation Committee, established by the fund's Board of Directors. A
fund may also fair value securities in other situations, such as when a
particular foreign market is closed but the fund is open. In deciding whether to
make fair value adjustments, the fund reviews a variety of factors, including
developments in foreign markets, the performance of U.S. securities markets, and
the performance of instruments trading in U. S. markets that represent foreign
securities and baskets of foreign securities. The fund uses outside pricing
services to provide it with closing market prices and information used for
adjusting those prices. The fund cannot predict how often it will use closing
prices and how often it will adjust those prices. As a means of evaluating its
fair value process, the fund routinely compares closing market prices, the next
day's opening prices in the same markets, and adjusted prices.

Currency Translation
Assets, including investments, and liabilities denominated in foreign currencies
are translated into U.S. dollar values each day at the prevailing exchange rate,
using the mean of the bid and asked prices of such currencies against U.S.
dollars as quoted by a major bank. Purchases and sales




of securities, income, and expenses are translated into U.S. dollars at the
prevailing exchange rate on the date of the transaction. The effect of changes
in foreign currency exchange rates on realized and unrealized security gains and
losses is reflected as a component of security gains and losses.

Class Accounting
The Advisor Class and R Class each pay distribution, shareholder servicing,
and/or certain administrative expenses in the form of Rule 12b-1 fees, in an
amount not exceeding 0.25% and 0.50%, respectively, of the class's average daily
net assets. Shareholder servicing, prospectus, and shareholder report expenses
incurred by each class are charged directly to the class to which they relate.
Expenses common to all classes, investment income, and realized and unrealized
gains and losses are allocated to the classes based upon the relative daily net
assets of each class.

Rebates and Credits
Subject to best execution, the fund may direct certain security trades to
brokers who have agreed to rebate a portion of the related brokerage commission
to the fund in cash. Commission rebates are included in realized gain on
securities in the accompanying financial statements and totaled $237,000 for the
six months ended June 30, 2004. Additionally, the fund earns credits on
temporarily uninvested cash balances at the custodian that reduce the fund's
custody charges. Custody expense in the accompanying financial statements is
presented before reduction for credits, which are reflected as expenses paid
indirectly.

Investment Transactions, Investment Income, and Distributions
Income and expenses are recorded on the accrual basis. Premiums and discounts on
debt securities are amortized for financial reporting purposes. Dividends
received from mutual fund investments are reflected as dividend income; capital
gain distributions are reflected as realized gain/loss. Dividend income and
capital gain distributions are recorded on the ex-dividend date. Investment
transactions are accounted for on the trade date. Realized gains and losses are
reported on the identified cost basis. Income distributions are declared and
paid by each class on an annual basis. Distributions to shareholders are
recorded on the ex-dividend date. Capital gain distributions, if any, are
declared and paid by the fund, typically on an annual basis.

Other
In the normal course of business, the fund enters into contracts that provide
general indemnifications. The fund's maximum exposure under these arrangements
is dependent on claims that may be made against the fund in the future and,
therefore, cannot be estimated; however, based on experience, the risk of
material loss from such claims is considered remote.




NOTE 2 - INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following
practices to manage exposure to certain risks or enhance performance. The
investment objective, policies, program, and risk factors of the fund are
described more fully in the fund's prospectus and Statement of Additional
Information.

Affiliated Companies
The fund may invest in certain securities that are considered affiliated
companies. As defined by the 1940 Act, an affiliated company is one in which the
fund owns 5% or more of the outstanding voting securities. At June 30, 2004, the
value of affiliated companies totaled $7,706,000, representing 0.2% of the value
of the fund's investments in securities.

Other
Purchases and sales of portfolio securities, other than short-term securities,
aggregated $1,733,651,000 and $642,264,000, respectively, for the six months
ended June 30, 2004.

NOTE 3 - FEDERAL INCOME TAXES

No provision for federal income taxes is required since the fund intends to
continue to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute to shareholders all of its taxable income
and gains. Federal income tax regulations differ from generally accepted
accounting principles; therefore, distributions determined in accordance with
tax regulations may differ in amount or character from net investment income and
realized gains for financial reporting purposes. Financial reporting records are
adjusted for permanent book/tax differences to reflect tax character. Financial
records are not adjusted for temporary differences. The amount and character of
tax-basis distributions and composition of net assets are finalized at fiscal
year-end; accordingly, tax-basis balances have not been determined as of June
30, 2004.

At June 30, 2004, the cost of investments for federal income tax purposes was
$3,035,033,000. Net unrealized gain aggregated $298,794,000 at period-end, of
which $365,770,000 related to appreciated investments and $66,976,000 related to
depreciated investments.




NOTE 4 - RELATED PARTY TRANSACTIONS

The fund is managed by T. Rowe Price Associates, Inc. (the manager or Price
Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. The
investment management agreement between the fund and the manager provides for an
annual investment management fee, which is computed daily and paid monthly. The
fee consists of an individual fund fee, equal to 0.35% of the fund's average
daily net assets, and the fund's pro-rata share of a group fee. The group fee is
calculated based on the combined net assets of certain mutual funds sponsored by
Price Associates (the group) applied to a graduated fee schedule, with rates
ranging from 0.48% for the first $1 billion of assets to 0.295% for assets in
excess of $120 billion. The fund's portion of the group fee is determined by the
ratio of its average daily net assets to those of the group. At June 30, 2004,
the effective annual group fee rate was 0.31%, and investment management fee
payable totaled $1,735,000.

The Advisor Class and R Class are also subject to a contractual expense
limitation through the limitation dates indicated in the table below. During the
limitation period, the manager is required to waive its management fee and
reimburse a class for any expenses, excluding interest, taxes, brokerage
commissions, and extraordinary expenses, that would otherwise cause the class's
ratio of total expenses to average net assets (expense ratio) to exceed its
expense limitation. Through the repayment date, each class is required to repay
the manager for expenses previously reimbursed and management fees waived to the
extent the class's net assets have grown or expenses have declined sufficiently
to allow repayment without causing the class's expense ratio to exceed its
expense limitation.

- --------------------------------------------------------------------------------
                                                 Advisor Class          R Class

Expense Limitation                                        1.10%           1.40%

Limitation Date                                         4/30/06         4/30/06

Repayment Date                                          4/30/08         4/30/08

For the six months ended June 30, 2004, each class operated below its expense
limitation.




In addition, the fund has entered into service agreements with Price Associates
and two wholly owned subsidiaries of Price Associates (collectively, Price).
Price Associates computes the daily share prices and maintains the financial
records of the fund. T. Rowe Price Services, Inc., provides shareholder and
administrative services in its capacity as the fund's transfer and dividend
disbursing agent. T. Rowe Price Retirement Plan Services, Inc., provides
subaccounting and recordkeeping services for certain retirement accounts
invested in the Investor Class and R Class. Expenses incurred pursuant to these
service agreements totaled $1,028,000 for the six months ended June 30, 2004, of
which $128,000 was payable at period-end.

Additionally, the fund is one of several mutual funds in which certain college
savings plans managed by Price Associates may invest. As approved by the fund's
Board of Directors, shareholder servicing costs associated with each college
savings plan are borne by the fund in proportion to the average daily value of
its shares owned by the college savings plan. For the six months ended June 30,
2004, the fund was charged $159,000 for shareholder servicing costs related to
the college savings plans, of which $113,000 was for services provided by Price
and $26,000 was payable at period-end. At June 30, 2004, approximately 3.09% of
the outstanding shares of the Investor Class were held by college savings plans.

The fund is also one of several mutual funds sponsored by Price Associates
(underlying Price funds) in which the T. Rowe Price Spectrum Funds (Spectrum
Funds) and T. Rowe Price Retirement Funds (Retirement Funds) may invest.
Neither the Spectrum Funds nor the Retirement Funds invest in the underlying
Price funds for the purpose of exercising management or control. Pursuant to
separate, special servicing agreements, expenses associated with the operation
of the Spectrum and Retirement Funds are borne by each underlying Price fund to
the extent of estimated savings to it and in proportion to the average daily
value of its shares owned by the Spectrum and Retirement Funds, respectively.
Expenses allocated under these agreements are reflected as shareholder servicing
expenses in the accompanying financial statements. For the six months ended June
30, 2004, the fund was allocated $185,000 of Spectrum Funds' expenses and
$34,000 of Retirement Funds' expenses. Of these amounts, $153,000 related to
services provided by Price and $30,000 was payable at period-end.




At June 30, 2004, approximately 6.2% of the outstanding shares of the Investor
Class were held by the Spectrum Funds and 2.1% were held by the Retirement
Funds.

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe
Price Government Reserve Investment Fund (collectively, the Reserve Funds),
open-end management investment companies managed by Price Associates. The
Reserve Funds are offered as cash management options to mutual funds, trusts,
and other accounts managed by Price Associates and/or its affiliates, and are
not available for direct purchase by members of the public. The Reserve Funds
pay no investment management fees. During the six months ended June 30, 2004,
dividend income from the Reserve Funds totaled $1,020,000.
