As mentioned in my Are we in a bubble? thread, PSA 9 1st Edition Neo Genesis Pichu has gone from $46 to $520 in 8 months: www.psacard.com/auctionprices/tcg-cards/pokemon-neo-genesis-1st-edition/pichu-holo/values/1761531#g=9. There are currently 4 of them up for sale on eBay right now and 4 have sold in the past month alone; a grand total of 7 of them sold on eBay in the entirety of 2019, so I don’t believe this to be anything to do with a lack of supply - more like a surge in demand for whatever reason.
