I picked up this 1909-s on the cheap. I need it to fill a spot in my Dansco but don't know much about corroded coins. I don't have perfect examples but am trying to get the best bang for my buck (don't have a large budget for coins). Will this get worse? Is there something I can do to keep the coin from getting worse? Should I try to sell it and get back my money and use on a nicer coin? Open to any suggestions on what I can do to help this poor coin.
