Amazing. I was looking over some trading card prices just recently. The market, especially for high-scoring PSA stuff, is insane. Lots of Basketball related cards can go north of 25,000 (type "Michael Jordan Tops PSA" in ebay) and they don't struggle to sell at that either. I sold a single Garbage Pail Kids trading card (2 actually) last month for £37 (each). They were in good condition but not quite mint. Mint PSA10 examples can go for way more.
