Is there a list of sellers and/or stores with a track record of selling/producing fake cards? Particularly Ebay...What are the most crazy or smartest tricks you have have come across?
Collecting tennis cards, I often see cards on Ebay that are rubbish homemade fabrications, not even close to being worth the ridiculous money that is asked for them. The images used are often to good to be taken by amateurs and probably copyright infringements too.
Other sellers are pretty smart. I'm suspecting one of having falsified certain cards by simply taking original base cards and somehow imprint super short print serial numbers in a diffierent colour, as if they actually existed. To my knowledge the parallel set he tries to sell does not even exist. And of course he owns most of these so called "inserts" but not all of them (which would be suspicious of course).
