The U.S. Treasury may end up minting coins to raise money for the Baseball Hall of Fame.

Sales of the commemorative coins would raise millions of dollars to help the hall mark its 75th anniversary in 2014.

Democratic Sen. Dick Durbin of Illinois is among the lawmakers backing the proposal, which would not cost taxpayers anything. The U.S. House passed identical legislation last fall.

The measure calls for the Treasury to make $5 gold coins, $1 silver coins and half-dollar coins. Sales of the coins would pay for the cost of making them and raise up to $9.5 million for the Hall of Fame.
