I am also in the someone ripped you off side. Negatives are very easy to copy or just make from a picture. I have made several and inserted them into custom cards I have made for others.
The no name slab is another huge red flag. Cool items just not worth more than a few dollars as novelty pieces.
I wouldn't take it too hard as I can guarantee we have all been screwed on items we wanted to be real or unaltered.
