It is worth that much for a 8-9, but for a PSA 6, not worth $4k in my opinion
It is not at all worth that much IMO.
The Population numbers right now for the 70k Umbreon is 11 10’s, 2 9’s and a 5+6. Clearly the card is a highly graded card, seeing as there are only a few even out there.
Id mention even to the seller they are trying to get top dollar for a card well below the standards of the 85% of 70k Umbreons that have been graded.
I believe to have gotten that Umbreon, you needed to attend almost every event in Japan for the 2005 season, it was all point based, there is a formula somewhere. Espeon has a pop 23, however when you are talking about these low pop, low release items, its almost hard to negotiate price as Id imagine 80% of all the cards are in collections and not on open markets. That’s why seller priced items are able to surface and never leave the market at crazy high prices. Sure its technically more rare, but in reality they are both in a class where everything is just super rare.
Definitely not worth that price at this point in time.
That said, the seller is pretty negotiable on the whole. I can’t imagine he’d turn down a reasonable offer on the card. Like @smellyblueberry said above me, you had to attend quite a few events to earn the Umbreon. And you had to be decent enough at the card game to earn points. It was pretty difficult to get this card.
I always wonder if there are more cards out there that were never awarded.
