This year?s two commemorative coin programs will see sales end Dec. 14, the Mint announced.
The Jamestown 400th anniversary of settlement silver dollar and $5 gold piece will conclude after having been on sale since January.
The silver dollar marking the 50th anniversary of desegregation of Central High School in Little Rock, Ark., has been on sale since May.
No other programs have termination dates officially designated yet, however, in December the Mint tends to sell off remaining supplies of bullion coins and sales then end without warning.
The Mint?s American Eagle distributors get a final shot at getting remaining 2007 coins and then orders are accepted near month?s end for the first of the 2008 coins, which are released at the opening of the new year.
In years of oversupply there can be sales of bullion coins from the prior year offered in the new year.
Annual sets normally remain on sale until the next annual set goes on sale.
Sales also end for any offer that reaches the previously announced maximum.
