Sen. Charles Schumer and Rep. Jerrold Nadler are asking for a crackdown on a Westchester company selling 9/11 commemorative coins supposedly made of silver from Ground Zero.

The two state lawmakers called yesterday for the Federal Trade Commission to stop Port Chester-based National Collector’s Mint from selling the coins.

The company is advertising the coins as “the officially authorized 10th-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 9/11 memorial that is being built at the World Trade Center site.

National Collector’s Mint President Avram Freedberg said the company has donated more than $2 million to various Sept. 11 charities.
