All prices below are pulled directly from PriceCharting’s public catalog and refreshed each time this article regenerates (typically weekly). PriceCharting computes their values from active and recently-sold listings on eBay + their dealer network — independent of any data on this page. The Sealed column reflects PriceCharting’s “manual-only” / new tier — factory-sealed retail at average condition; specific graded-sealed prices vary sharply by numeric grade + seal letter (use the Sealed eBay browse link below for grade-specific comps).

• Complete in Box (CIB): $92

• Sealed: $230

Heritage Graded Sales

Heritage Auctions sold results below are real auction transactions for Serpent 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 Serpent Matters for Grading

PSA has graded only 4 copies of Serpent 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. Notable: every graded copy is in the sealed condition — collectors clearly favor that condition tier for this title, and the other conditions are either ungraded territory or grade-and-flip opportunities. Sealed copies trade at roughly 9× the loose price ($230 vs $23). Solid spread for grading speculation if you can source a clean sealed cart.

Frequently Asked Questions

Is Serpent Game Boy worth grading?

Strong yes for clean copies. With only 4 graded copies on record, Serpent 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 Serpent?

PSA tracks 4 graded sealed copies of Serpent 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 Serpent?

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 Serpent?

PSA’s database currently shows one tracked variant for Serpent 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.
