Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for SeaWorld: Shamu’s Deep Sea Adventures on Game Boy Advance. 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 SeaWorld: Shamu’s Deep Sea Adventures Matters for Grading
Exactly one PSA-graded copy of SeaWorld: Shamu’s Deep Sea Adventures for Game Boy Advance exists on the population census.

Frequently Asked Questions
Is SeaWorld: Shamu’s Deep Sea Adventures Game Boy Advance worth grading?
Strong yes for clean copies. With only 1 graded copies on record, SeaWorld: Shamu’s Deep Sea Adventures is squarely in the rare-population tier for Game Boy Advance — 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 SeaWorld: Shamu’s Deep Sea Adventures?
Exactly one — 1 PSA-graded sealed copy of SeaWorld: Shamu’s Deep Sea Adventures on the census. Population-one rarity for collectors who care about that distinction.
Should I buy a graded or raw copy of SeaWorld: Shamu’s Deep Sea Adventures?
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 SeaWorld: Shamu’s Deep Sea Adventures?
PSA’s database currently shows one tracked variant for SeaWorld: Shamu’s Deep Sea Adventures on Game Boy Advance. 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.
