You are bidding on item listed. A Rare Ohio State Buckeyes 1870 Hockey Puck. I am unsure on the date. My guess would be the 1960's or 70's but I'm not sure. This and the other one I have listed are the only ones I could find on the internet. I believe "1870" stands for the NIL program. That program dates back to the 1930's. It looks great and doesn't look to have been used. A great addition to your collection. Thanks for looking.
