Welcome to CT Kimmi. Many years of the Buffalo Nickel, were poorly struck and I see the rear right leg almost missing, along with an almost smooth bison head, but not from wear. In the Mega Red book, it goes into depth on strike quality and worth the read. For additional posts, you will get more responses by posting correctly orientated, in focus photos of the full obverse and reverse of your coin, and close ups of areas in question.
