Youtube suggested a video to me about what's going on in the collectable video game market. The claim was that there's some collusion between a major auction site and a grader, and some of those players were running a pump and dump. Unless you know who the buyers and sellers are or transaction fees are high (like an auction at Christie's), you have no idea if the sales are real, so it's pretty easy to make it look like the asset is appreciating when it's really just manufactured hype.
