Howdy, Came across this Morgan from collection mom gave me in 1979. Other than playing with the coins as a kid I put them away and just now going through them. She had them put away since 1948 before giving them to me. Wedding gift of 300 silver morgans and peace dollars from grandpa to start a life. Just wanted to give history of the coins that have not been in circulation for 72 years. I can't find anything about the doubling on reverse and need help so I can label before putting back in storage. Thank you
One way to remember is if the second impression is shelf-like, than it MD or machine doubling for the most part .
You can check through your Morgans and Peace dollars on this site. The link is for the 1880-O. On the index page there are separate listings for Morgan dollars by date and Peace dollars http://vamworld.com/wiki/1880-O_VAMs
