President-Elect Barack Obama "Commemorative Coins"
Source: The New England Mint
Not colorized by the United States Mint
It has come to the attention of the United States Mint
that several private commercial businesses are
advertising so-called "Barack Obama Presidential $1
Coins," as well as commemorative half-dollar coins,
American Eagle Silver Coins and multi-coin sets
bearing images of the President-Elect. These
advertisements feature genuine United States coins
that the private commercial businesses have altered
by affixing a colorized image to the coin.
Additionally, some businesses have treated the coins
by gold-plating them.
These items are not official United States Mint
products. Furthermore, these products, businesses,
and advertisements are not approved, endorsed,
sponsored, or authorized by the United States Mint,
the Department of the Treasury, or the United States
Government.
The United States Mint receives frequent inquiries
from the public concerning its position on the
industry practice of superimposing colorized
images-such as those of prominent public figures,
celebrities, or cartoon characters-on genuine
United States coins. The United States Mint does
not encourage, endorse, or sponsor products that
alter the fundamental images depicted on its coins.
Congress itself mandates by statute the design
themes and inscriptions that appear on United
States coins. A superimposed image is entirely
different from and obscures the coin's original
design.

Nothing in there about "so don't do it". They don't like it but it appears
to be not against the law.
