The weight is off by almost a full gram as you can see, also diameter is a few hairs smaller as well. Value if any???
How would one know for sure its a foreign planchet or undersized? Is there a big difference? Thanks!!!!
I agree with those that said acid . this coin has been dissolved some in acid or lost underground for a long time and corroded away , then found and the corrosion cleaned off.
For what it's worth, here a quick explanation of acid dipped coins: http://www.coingalaxy.com/coininfo/acid.html
Is anyone out there sick and tired of seeing acid treated coins posted on the various forums? Whoever "invented" this post mint damage type should be put in jail. Sorry....just venting a little.
