I was never into graded cards but was thinking about starting a collection of baseball and football RCs in the PSA 8-9 range that tend to sell upwards of $25. Well after doing research it seems the cheapest ones on COMC are still twice the going rate on EBAY. If this was some rare card that is hardly ever seen, that's one thing. But for multiple cards that sell daily, I don't get what sellers at COMC are trying to prove. And in many cases, guys want more for their PSA8s than what PSA9s sell for on EBAY, example is the Stadium Club Murphy Jeter. I'm guessing there are reasonably listed RCs but they sell out real fast? Would it be simpler just to cash out and buy the cards on EBAY?
