My wife handles thousand of quarters each month. She uses CoinStar and brings home any coins that the machine rejects. Sometimes Canadians or Bermudas. Sometimes a perfectly acceptable US coin is kicked out. This quarter is something I've never seen. The obverse shows a beat up dirty face with tell tale tourquoise around Washingtons head. From the side it shows the same tourquoise but the middle copper, or whatever the devil it is, is missing and deep enough to put a fingernail or a knife edge into. These are the best pics I can manage. Opinions on what happened to this coin.
You need to post better pics then that in order for us coin guys to determine what that is. sorry Jazzcoins Joe :whistle:
From your description, and what can be seen in your photos, I would say it was attacked by an acid that ate away the copper core around the edge and damaged the surface of the coin. Or, it could have been whatever caused this:
Your images nailed it David. There's a bit of blue corrosion around the edges of my quarter but it's remarkably close to your pics.
What date is yours, Sined? David's is a 1965 and I was wondering if yours might be the same date, which would lend credibility to it possibly being post mint. Ribbit
1976. I assumed post mint damage from the start but I'm open to any ideas. I'll add I worked with copper wires for Ma Bell. Corrosion of the bright tourquoise type usually occured when conducters became wet. Water + electricity caused bright blue corrosion.
