Mickey mantle Auto Memoribilia Question

07diedrt

I am looking for a person with vast knowledge in Mantle autographed memoribilia. I have a piece that I have no idea what it is worth and I am very interested in selling/trading it, but would like to get an idea of how much it is worth before I pull the trigger on anything. Figured I would ask here since there are a lot of knowledgeable people here. I can send pictures of the piece through email if you think you could help. Email me @ diedricht07@gmail.com
