Why Mystical Ninja Starring Goemon Matters for Grading
PSA has graded only 4 copies of Mystical Ninja Starring Goemon for Game Boy across all conditions — a tiny population that puts collectors who own a graded copy in a roster of fewer than 9 known holders. The sealed condition dominates submissions (3 of 4, ~75%) — a strong signal that’s where most collector value sits for this title. The sealed-to-loose price ratio is roughly 16× — sealed copies trade at $976 while loose carts move around $58. That spread means a fresh sealed find is the move; raw cart flips have thinner margins after grading fees.
Frequently Asked Questions
Is Mystical Ninja Starring Goemon Game Boy worth grading?
Strong yes for clean copies. With only 4 graded copies on record, Mystical Ninja Starring Goemon is squarely in the rare-population tier for Game Boy — and PSA grading adds meaningful provenance on titles with this little supply. Grade-and-hold is the play; flipping mid-grade copies thins margins fast.
How rare is a graded sealed copy of Mystical Ninja Starring Goemon?
PSA tracks 3 graded sealed copies of Mystical Ninja Starring Goemon for Game Boy. The grade-tier breakdown above shows how those split across PSA’s numeric grades — top-grade copies (9.4+) are the scarcest and typically command the strongest premiums.
Should I buy a graded or raw copy of Mystical Ninja Starring Goemon?
Depends on your goal. Graded copies cost more upfront but come with PSA’s authenticity + condition guarantee — the right move for buy-and-hold collectors. Raw copies are cheaper but require condition assessment yourself, and the grading lottery means a $50 raw cart can come back as a $25 PSA 7 OR a $200 PSA 9.4. Use the per-condition pop and price data above to calculate expected value before you commit.
Why does PSA track multiple variants of Mystical Ninja Starring Goemon?
PSA’s database currently shows one tracked variant for Mystical Ninja Starring Goemon on Game Boy. That doesn’t mean only one variant exists — production codes that haven’t been submitted yet won’t appear on the census. Check the back of your cartridge for production-location markings (“Made in Japan”, “Made in Mexico”) and the box for ESRB-rating placement to identify your specific variant.
