I meant double strike? But I couldn't edit it, sorry. Any how Ihave a few quarters like this, even cleaner that seems to have an inner ring like a 2nd lighter stamp? Any thoughts on what or why?
No my friend those marks comes from a counting machine, or the quarter being an end of roll coin and the maching that seals the roll makes those marks. Sorry to pop your bubble.
Anytime you see those types of circular marks on a coin consider it damaged by a coin rolling machine. Welcome to CT.
