Original Goodyear Poly glas tires

[69SSRSL89]

I have a set of original Goodyear F70 14 poly glas tires that I picked up earlier this summer and thought that they where used reproductions. I was thinking of using them to cruise around on but I would hate to waste a set of original dated tires. They are in good used shape. They are not perfect but they are still nice and have a good amount of tread on them. Does anyone know what the value on something like this would be and if there would be any interest in them? I'm not looking to make a killing off of them. I'd just rather sell them to someone that wants the dated originals than wear them out. I didn't post this in the for sale section since I'm unsure of the value and also interest. Thanks for all of you help in advance. Jesse
