Coin silver was once a common alloy in the United States. It is now relatively rare and the name causes some confusion. The technical “coin silver” alloy is .900 argento, O 90% argento e 10% rame. It was not used to make coins, but at one point in time it was made from refined scrap coins. Le monete monetarie nel nostro Paese, e molti altri, no longer contain silver and are made from more inexpensive and durable base metals. I gioielli in argento con monete ancora sul mercato porteranno il marchio di qualità .900, and they are rare antiques.
