Old and not so old FFG magazine value????

I have FFG dating back to the 40's. Several singles in the 50's, but most of them are 60's, 70's, 80's. I plan to sell these at the FTA in Iowa. I would appreciate any help on pricing. I know that is a tough one so what if a value estimate was for magazines in good shape, and also a value for complete years. Thanks for any help, Mark.

Prices for excellent condition magazines,,complete no torn pages,,cut out ads,,covers intact,,no tears or stains,,,really nice,,,lesser condition price goes down fast,,,these are retail,,,if you sell in quantity be prepared to discount,,,good luck selling and have fun at the FTA

1940's,,,$5--7 each
1950's,,,,$3-4 each
1960's,,,,$2 each

Newer are hard to sell

There is a 1950's with Fred bear on the cover it can go for up to $25 in mint condition

Thank you for your help. I'll hang on to that info for sure. Thanks again, Mark
