Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for Conquest of the Crystal Palace on Nintendo NES. 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 Conquest of the Crystal Palace Matters for Grading
PSA has graded only 8 copies of Conquest of the Crystal Palace for Nintendo NES across all conditions — a tiny population that puts collectors who own a graded copy in a roster of fewer than 13 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. The sealed-to-loose price ratio is roughly 10× — sealed copies trade at $357 while loose carts move around $33. That spread means a fresh sealed find is the move; raw cart flips have thinner margins after grading fees.
Frequently Asked Questions
Is Conquest of the Crystal Palace Nintendo NES worth grading?
Strong yes for clean copies. With only 8 graded copies on record, Conquest of the Crystal Palace is squarely in the rare-population tier for Nintendo NES — 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 Conquest of the Crystal Palace?
PSA tracks 8 graded sealed copies of Conquest of the Crystal Palace for Nintendo NES. 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 Conquest of the Crystal Palace?
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 Conquest of the Crystal Palace?
PSA’s database currently shows one tracked variant for Conquest of the Crystal Palace on Nintendo NES. 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.
