Representative Jerry Nadler of New York just introduced legislation today suggesting that in 2011, the United States Mint create a coin marking the tenth anniversary of the September 11 attacks. The coins — which would bear the words “Always Remember” — would be minted in New York and Pennsylvania, and the proceeds would go to the National September 11 Memorial and Museum at the World Trade Center. They’d cost a total of $10, which raises the question: Does this mean the $3 coins Aunt Helen bought from a street vendor downtown five years ago while she was visiting from California are going to appreciate in value?
