I bought a couple from shoe heart on ebay this year as well for the variety and because they actually look really cool. There was no competition on either when I bought them, which surprised me. I thought there would be, but maybe since they were so unusual, maybe people thought they were home made or fake some how.
They are all the same glossiness and there is no missing layers that the naked eye could detect. mine have some light creasing, similar to what i have seen on sheet cut cards. I'm guessing this was some sort of test sheet that made it's way into someone's hands to be cut and sold later on.
