@numismatist6, I think that there was some damage to the rim followed by circulation wear and therefore it is hard to tell if there was also a cud when this guy left the mint. This particular area, if a cud, would be a little unusual in shape. As it turns out, there is not a single example of a Walking Liberty with a cud on the cuds-on-coins website. My advice is to contact them and let them decide what they think it is. If they agree cud, then you will have not only a pic on their website, but the entire category to yourself.
