And the price of the SP's jumped to appropriate levels in the Price Guides as well. Back in the 1980's whenever I had one of the tougher 1967 Mets Hi# and priced them at $15-20 the question would be,, but the Book say the card is XXX.
My 1st standard response was to give the address listed in the Beckett Price Guide and send them a check for the card. My 2nd standard response -- was: BTW -- how long have you been looking for this card? Usually the answer was 4-5 years which my response would then be -- and then you wonder why the card is priced so seemingly high.
By 1991-92 most of those cards were properly priced in the guides
