Carbon spots? | Coin TalkAug 02, 2008 · Yes, the tiny carbon deposit in the metal alloy oxidizes in the air. And while almost any dark spot on any coin is commonly called a carbon spot, in most cases it is not really a carbon spot - they are just called that. True carbon spots are most often found on copper because there is a lot of carbon in copper. OK, that makes sense.
