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 sølv, eller 90% sølv og 10% kobber. It was not used to make coins, but at one point in time it was made from refined scrap coins. Monetære mønter i vores land, og de fleste andre, no longer contain silver and are made from more inexpensive and durable base metals. Møntsølvsmykker, der stadig er på markedet, vil bære et kvalitetsstempel af .900, and they are rare antiques.
