Thank you everyone for your time! I am new to collecting and will have many questions in the future. Just starting to go through Dad's collection and learning as I go. Also learning the ropes with the USB microscope. Is the 1975 doubled here? It looks much different than my last post which was die wear. Thank you again everyone!
Hi and welcome:) I had an email that helped me better understand what to look for in doubling. He said to look for splits/notches in the serifs. This helped me alot! http://doubleddie.com/58222.html this is a site I use as my numismatic study. Good luck and enjoy the hunt!
Also the dies were way over polished. It reduced the normal size of the digits a lot. https://www.PCGS.com/coinfacts/coin.../images/2977 This is what size it should be. MD covered about half of the size of the thinned digits. The DDO is huge compared with the OP's coin.
