Pichu Arcues Illustrator cards

Does anyone know how much these cards are worth individually? There is a seller on ebay who just listed a bunch for $250 each. Is that a great deal or too much and is there are market for them?

Lol well these illutrator sets took a hard fall. There have been sets on yahoo japan that go for less than $700 for a whole set now

So an individual card shouldn’t sell for more than $100?

I wouldn’t pay more than $700 for a set making each card no more than $70 each.

Glad I asked first. Thank you
