Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for Ken Griffey Jr. Presents Major League Baseball on Game Boy. They complement the PriceCharting loose / CIB / sealed benchmarks above; they are not estimates and they are not blended into PriceCharting’s ungraded market prices.
Summary rows are title-level Heritage sale signals, sorted by format, recency, and realized-price signal. PSA production variants can price differently, so the sale records keep Heritage’s own variant notes visible instead of pretending every auction lot maps cleanly to a PSA variant row.
High-grade games can trade years apart, so older auction records stay visible; treat the latest-sale date as part of the comp, not just the dollar amount.

Why Ken Griffey Jr. Presents Major League Baseball Matters for Grading
With 15 PSA-graded copies on record, Ken Griffey Jr. Presents Major League Baseball 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 (14 of 15, ~93%) — a strong signal that’s where most collector value sits for this title. The sealed-to-loose price ratio is roughly 24× — sealed copies trade at $217 while loose carts move around $8.94. 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.
Frequently Asked Questions
Is Ken Griffey Jr. Presents Major League Baseball Game Boy worth grading?
Mostly for sealed copies. The sealed-state population (14) outweighs CIB and loose for Ken Griffey Jr. Presents Major League Baseball, indicating sealed is where collector capital concentrates. CIB and loose grading is viable but margins are thinner after fees.
How rare is a graded sealed copy of Ken Griffey Jr. Presents Major League Baseball?
PSA tracks 14 graded sealed copies of Ken Griffey Jr. Presents Major League Baseball 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 Ken Griffey Jr. Presents Major League Baseball?
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 Ken Griffey Jr. Presents Major League Baseball?
PSA recognizes 2 distinct production variants of Ken Griffey Jr. Presents Major League Baseball on Game Boy. Variants reflect real production differences — different factories (Made in Japan vs Made in Mexico), packaging die changes, ESRB-rating retrofits added partway through the console’s life, or Players Choice reissues from later runs. Collectors price them differently because rarity diverges, and PSA tracks each on its own population row so the data reflects the real market structure.
