The E-Sylum: Volume 4, Number 2, January 14, 2001, Article 7


Web site visitor Rafael Delgado asks:

"Would any solid metal (not clad) coin minted in the Philadelphia Mint have a specific gravity between 6.9 and 7.3 ? Would you remember any reference magazine that published an article about experimental metals during the period 1973 to 1980?

I am looking specially to the period from the 1973 copper shortage to mid 1980 due to a coin that exhibits a metal not compatible with any metal reported by the US Mint (neither foreign nor domestic) in the resources at hand: "Specifications of US coins" from Coin World Almanac, and "World Coins Minted by the US Mints" from the 2001 Blackbook. It seems an experimental metal for the Susan B. Anthony dollar or a counterfeit. My interest is determining which it is."

Perhaps one of our astute subscribers is aware of such a piece or a reference to it.
