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 silver, eller 90% silver och 10% koppar. It was not used to make coins, but at one point in time it was made from refined scrap coins. Monetära mynt i vårt land, och de flesta andra, no longer contain silver and are made from more inexpensive and durable base metals. Mynt silversmycken som fortfarande finns på marknaden kommer att bära en kvalitetsstämpel av .900, and they are rare antiques.
