Fairly green to collecting. Searching for answers
Hi there I have a few coins I have questions about. I have held onto a few coins and am always checking through any circulated coins I come across. I have a few I have questions about there value and whether or not they are recognized errors. Any help is greatly appreciated. I have a 1977 circulated memorial penny with what looks like a reverse Double die or double strike? A 2009 lincoln penny with the same on obverse and reverse. A 2020 quarter with double die or strike on "In god we trust and "dollar" and last but not least 1982D lincoln penny which I am pretty sure by the sound and teeter method of weight might be copper? With a die chip between RI in america on reverse? Opinions or comments are greatly appreciated. Thank you!
