Opened up the last one I received today and low and behold I found lots of black what I assume was polishing compound around the rim. Popped the coin out and saw a raised edge covering about half of the ironworker side of the coin. So I took the best pics I could of it and would like some opinions on it. I guess I would call it a slight off center strike? This is definitely a raised edge on the coin and not easy to get pics of how raised it is. I don't think I'll be sending this one back and wonder if NGC would attribute it as a mis-strike of any kind.
I posted about the same thing. https://www.cointalk.com/threads/2015-coin-and-currency-set-error.268064/
After I posted I began to wonder if that's what it was. I remember reading the earlier thread about it. I have now found it on several of the new Sacs in the sets but this one was so far the most prominent.
