Interesting lot up on Goldin right now- 12 graded (PSA 7) 1967 Topps Mickey Mantle cards. According to Card Hedge, the last PSA 7 to sell went for $810 (just yesterday).

Would a person buy these to keep all 12 or try and swoop in to get them for a bargain and flip? There are 11 days left on the sale and with the buyer's premium, the average card price is currently $635.
