The best vintage cards to grade in 2026 include 1952 Topps Mickey Mantle (PSA 9 = $12.6M), 1986 Topps Jerry Rice rookie (PSA 10 = $90,000, 40x PSA 9), 1951 Bowman Willie Mays (undervalued vs Mantle), 1976 Topps Walter Payton (PSA 10 = $81,000), and 1989 Upper Deck Ken Griffey Jr. (PSA 10 = $2,030, 11.6x PSA 9).

The PSA population report at psacard.com/pop shows how many copies of every card PSA has graded at each grade level. Calculate gem rate (PSA 10 count / total graded x 100) to identify scarcity. Under 5% gem rate = major condition scarcity. Under 1% = trophy asset. Use pop data to decide which cards to grade, buy, and sell.
Cracking a slab for regrading is worth it when the card was graded in a looser era (pre-2018 or 2019-2021), the PSA 9-to-10 price gap exceeds $500, AI pre-grading predicts 70%+ PSA 10 probability, and the expected value is at least 2x the all-in cost. Use crossover service instead of cracking for lower risk. Never crack vintage cards or cards worth under $100.
The best MTG cards to grade in 2026 include Alpha/Beta rares (PSA 10 = 50-500x raw), Power Nine (authentication essential), Reserved List staples like dual lands, Lord of the Rings showcase foils (PSA 10 = 132x raw), and serialized Ravnica Remastered cards. BGS is the top choice for MTG. CGC leads for modern MTG. Use AI pre-grading to identify PSA 10 candidates.

A PSA 10 typically sells for 2-10x more than a PSA 9 of the same card. The premium ranges from 1.5x on common modern base cards to 80x on rare vintage gems.
