Found this today, looks like the effected area was already there before striking.

@Walter Marx
Do you ever look at any other threads here on CoinTalk?
There are many with answers to all of your questions. Take time to look at them and learn what the different Mint Errors are. I have like 5 threads I created on Coin Laminations alone.

 

Nice lamination error

 

I do check out other threads, I like to I know little but always hesitate to proclaim a coin jave a certain error I guess because I'm not always 100% sure. Next time I post I'll take that step and give my best logical description of the error and hope to be right. Thank you paddyman, sincerely! ⏰

 

don't forget to place the coin on a well lit, flat surface.

I think the russians have now stolen your finger prints.

 

OK then, That's great. You are welcome.

 

Yaaay! I diagnosed this one correctly!!
