That looks like a fake. I recognize that full card foil pattern (which never happened on those earliest sets) from a fake Fossil Grimer sticker I have. Another giveaway is that everything on the card is on the opposite side of the card it should be for Japanese cards.
If you compare it to a legitimate Pokemon card, it should be slightly smaller than the legitimate card. And it'll peel off like it's a sticker.
So, it's not worth anything at all.
