I have two uncut sheets Topps 1971 and 1972. I'm planning on listing them on ebay but I can't find anything similar there to compare them to. I thought maybe board members would some idea on a good ballpark value. I have photos below. They are not in very good condition as they've been stored rolled up for the last 45 years, and have creases and significant edge wear.
Any advice appreciated!
