Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for The Mutant Virus 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 The Mutant Virus Matters for Grading
With 28 PSA-graded copies on record, The Mutant Virus sits in the mid-rarity tier for Nintendo NES — graded copies surface periodically on eBay but command meaningful premiums over raw. The sealed condition dominates submissions (26 of 28, ~92%) — a strong signal that’s where most collector value sits for this title. Sealed copies trade at roughly 5× the loose price ($255 vs $49). Solid spread for grading speculation if you can source a clean sealed cart.
Frequently Asked Questions
Is The Mutant Virus Nintendo NES worth grading?
Mostly for sealed copies. The sealed-state population (26) outweighs CIB and loose for The Mutant Virus, 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 The Mutant Virus?
PSA tracks 26 graded sealed copies of The Mutant Virus 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 The Mutant Virus?
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 The Mutant Virus?
PSA’s database currently shows one tracked variant for The Mutant Virus 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.
