Original used upholstery 69-70

[Bluesman]

I just did my interior over the front bucktes were shot but the rear is still in usable shape no rips, stains etc

would a used but decent rear set of original 69-70 deluxe upholstery be worth anything.
I dont see listings on ebay other than for new. so before I toss this do you think it can be sold and for how much
