I found this coin last night and did some research on it. I found an article that said the first one found was a 2001 from the Philadelphia mint. When my coin is set on the reverse side down the coin will spin like a top if you spin it, it also rocks when set reverse side down. The obverse appears to be normal because it lies flat and doesn't spin or rock. I wanted to know if anyone can give me more information about this? Thank you! Here are pics.
It's possible that its simply bent as I see no reason why it would be Convex. The 2001 coins are convex because there is a severe die crack that includes nearly all the stars on the reverse. The reverse die itself was close to exploding on the press. This "crack" pushed the center section of the coin out causing the convex appearance. Its a remarkable error coin.
Lyds... Would there be any way to tell if it is bent? Could I lay it on its obverse and push down on the rim with one finger and see if it rocks, but do this to all points along the rim to see if there is rocking? Here is a video of me spinning the coin. I think it may be bent too but wanted other opinions.
I'd be happy to examine it for you at no charge. It would be very cool if this is another example of a sunken die error affecting the entire die face. Not all sunken die errors are accompanied by cracking. By the way, the 2001-P half dollar was struck by reciprocally deformed, convexo-concavo dies. While the reverse die sank in (producing a bulging reverse on the coin), the obverse die bulged out slightly, producing a slightly sunken obverse face on the coin. The error half dollar will rock when its reverse face is placed on the obverse of a normal 2001-P half dollar, but it is stable when resting on the obverse of another error 2001-P half dollar.
Thanks for the offer Mike! I would love to have you examine this coin. I am a CONECA member and wanted to know if you want me to send it to your address in the back of the CONECA newsletter?
