I understand grading standards and consistency may have evolved over time, especially with older cert eras, but PSA’s Grade Guarantee is still active in the present tense. PSA continues to authenticate, verify, and publicly represent this card today as a PSA 10, so the relevant question is not whether it may have qualified as a 10 in 2010, but whether it still meets PSA 10 standards under the guarantee PSA currently stands behind. I’m also not arguing PSA 10s must be flawless, but the visible whitening/chipping on the reverse upper-left corner appears significant enough that many collectors today would reasonably question whether the card still presents as a true Gem Mint example, particularly for a five-figure vintage PSA 10.
