NEW YORK (AP) — Two New York lawmakers are asking for a crackdown on a company that is selling Sept. 11 commemorative coins supposedly made of silver from ground zero.Sen. Charles Schumer and Rep. Jerrold Nadler called Monday for the Federal Trade Commission to stop Port Chester, N.Y.-based National Collector's Mint from selling the coins.The company is advertising the coins as "the officially authorized tenth anniversary September 11th commemorative." They sell for $29.95.But Schumer and Nadler said the coins are not sanctioned by any government agency and have no connection to the Sept. 11 memorial that is being built at the World Trade Center site.National Collector's Mint President Avram Freedberg said in a statement that the company has donated over $2 million to various Sept. 11 charities.
