Thinking of selling these. Would they sell?

Hello all,

I'm a graphic design student, and recently put together this project where I repackaged and relabeled used 7-inch singles in custom riso-printed and letterpressed packaging. It was all done by hand, and was a lot of fun.

There are three designs, one for the 60s, 70s, and 80s. You don't know what song you'll get unless you play it.

I also hid 7 different ciphers throughout the packaging that you can decode for little hidden messages.

I'm thinking of doing another round and selling them on Etsy or something. How much would you pay for these? Any thoughts on this product or how I should market it?
