Buy/Sell/Trade Forum

I hope th iui visits right forum I'm posting in.  I have a old 70's baseball card case in excellent condition that open on both sides and then has divided sections that seperate cards by team names....The cards are sets from 76 77 78 including Nolan Ryan (3) , johnny bench, rookie pitchers, rookie strike-outs , etc. All the cards in excellent shape - centering isnt so great on many cards though- not all but a few.  What would be fair to ask for these as a set?  There are also 1960's mixed in and a few 75' and 72' I think? I put up for sale and put make offer and got over 50 responses.. but, not sure what is fair offer.

Did you put these on ebay or somewhere else?

Are all 3 (76-78) Sets complete?

78 set is complete...77 and 76 not...all are in very good condition....

I put them on local facebook marketplace  buy/sell groups...in AZ
