I've been told by a dealer that this occurred outside the minting process but I found it in a sealed roll of 2006D Jefferson Nickels. Any thoughts? The reverse has some of this but the obverse was extreme. Struck through grease? Sorry about that loose "puppy" hair. Thanks!
Thanks Chris and thanks all. I'll throw it back to roll searchers and let someone else find out something new like I just did. You folks always are great!
