In the population report of Card X, there are 60 copies of each PSA grade except for PSA 1 for which only 1 copy has ever been graded. The sellers of PSA 2 cards are asking $40. The sellers of PSA 3 cards are asking $60. The seller of PSA 4 cards are asking $80, etc. After four years, the PSA 1 appears on ebay. Supposing that the card is one that you enjoy, How much would you pay for it?
