It was not used to make coins, but at one point in time it was made from refined scrap coins. العملات النقدية في بلادنا, ومعظم الآخرين, no longer contain silver and are made from more inexpensive and durable base metals. المجوهرات الفضية التي لا تزال معروضة في السوق ستحمل ختم الجودة .900, and they are rare antiques.
