Hey @rustedharmony , just a kind reminder that all buy threads require a price. Perhaps if you put a price on what you mean by “reasonable” prices then it may fish a copy out.
Otherwise, what the other members say is true. There’s a copy listed previously available on yahoo japan, for 1.5 million yen, which you can see here: page.auctions.yahoo.co.jp/jp/auction/n267991667 However, the listing has expired but I do see it relisted from time to time.
While you do make a good point that the price is pretty much what a collector is willing to sell the card for, supply/demand does affect the card, and this card has a well known popular status in which many collectors strive to get. This is not just a rare card, but a card that rarely pops up on the market with many buyers being interested:

Also from the top of my head, I do remember this card being sold in the four figure range in the past. Hope this helps!
