Why Teenage Mutant Ninja Turtles II: Back from the Sewers Matters for Grading

With 30 PSA-graded copies on record, Teenage Mutant Ninja Turtles II: Back from the Sewers sits in the mid-rarity tier for Game Boy — graded copies surface periodically on eBay but command meaningful premiums over raw. The sealed condition dominates submissions (24 of 30, ~80%) — a strong signal that’s where most collector value sits for this title. The sealed-to-loose price ratio is roughly 25× — sealed copies trade at $464 while loose carts move around $18. That spread means a fresh sealed find is the move; raw cart flips have thinner margins after grading fees. Because PSA tracks 2 variants separately, production-code identification matters before submission. The pop-by-variant breakdown above tells you which variant is the rarer find.
