1968 Topps Jerry Koosman / Nolan Ryan #177

Two Mets rookies share a card, but only one becomes legend

The 1968 Topps #177 rookie card pairs Jerry Koosman with Nolan Ryan, whose eventual 5,714 strikeouts and seven no-hitters make this one of the most sought-after cards of the era. Koosman was no afterthought himself, anchoring the Mets rotation and helping deliver the 1969 championship. This PSA 7 grades as Near Mint with the (OC) qualifier noting off-center registration, a common trait on the issue that keeps it well short of pack-fresh while still presenting cleanly for the grade.
