Found this unique bit during a search today. Looks like a poor man's double die, or lamination, or both? Obverse and reverse lamination with what appears to be doubling with die cracks as well. Any thoughts on this coin. Either way, it is one ugly copper.
The proper terminology is Doubled Die not Double Die, Big difference Quote - "Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology." closed quote I want to share this webpage with you - https://en.wikipedia.org/wiki/Doubled_die
A dip in acetone might find you removing a lot of what looks like built up something or other really. Don't want to dash your hopes but the scratches have ruined any value to this coin even if it is a lamination error. JMHO.
That is not THE 1955 doubled die that is heavily sought after. The DD stands out so much you would know by just looking at it. In other words, having to ask us pretty much confirms it's not the one. Photos definitely confirm though.
That will come off with and acetone soak to loosen things up and prying at it with a flat-head screwdriver. Don't worry, you won't lower the value of this coin doing that.
