‘Error’ Coin Inquiry at Mint

The U.S. Mint is reviewing security procedures at its Denver branch, a spokesman said Wednesday, amid published reports that some potentially valuable “error” coins were found in employees’ lockers and toolboxes.

The error coins, which are often ones struck twice, are sometimes considered very valuable to coin collectors.

“As part of an ongoing evaluation of our procedures, the U.S. Mint recently conducted a review of the Denver facility,” U.S. Mint spokesman Michael White said.

“At this point all we are authorized to say is that we’re going to follow up on some findings,” he said. But White would not comment on a published report on Coin World’s Web page that quoted a source saying error coins were retrieved at the Denver mint.

Last year a Philadelphia Mint employee was prosecuted for allegedly stealing error coins and selling them to dealers.
