I found this in the till this morning. It appears to be a split planchet. Half of the reverse of the coin is smooth but the other half is rippled. I'm guessing it's a split planchet. Any comments or observations would be helpful.
I'm thinking intentional pmd. I don't like those marks on the back. Looks like a tool marred it at several spots.
My first thought as well. But, in hand the smoother side is almost like a blank planchet, the rippled side is similar to split planchet coins I've seen at shows. It would be easier to determine if there was some evidence of striking on the rippled side.
Looks like someone used a belt sander on it. I can't tell if its just the picture but the missing part of the coin looks partially angled to me? Is the date found on the grinded side of this coin?
Dang, I wanted to know the year of this coin... Oh well! I don't even understand how some of these coins can continue around in circulation.
I don't know why, but this thread has made me hungry for hamburgers. I'll have to go to the market to buy some grinded beef.
Very nice. Here are some better scans of mine... I guess it's impurities that exist in a sheet of metal, between its layers, prior to the blanks/planchets getting punched out off it. Sometimes these impurities cause separation after the blanks/planchets are punched out, other times it takes a coin press to cause the seperation. Hence, the Split Planchet before and after strike errors. At least that is my understanding of it. http://www.coin-collecting-guide-for-beginners.com/how-coins-are-made.html http://lincolncentresource.com/Errors/Split_Planchet.html
