Heritage Graded Sales

Heritage Auctions sold results below are real auction transactions for George Foreman’s KO Boxing 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 George Foreman’s KO Boxing Matters for Grading

With 14 PSA-graded copies on record, George Foreman’s KO Boxing sits in the mid-rarity tier for Nintendo NES — graded copies surface periodically on eBay but command meaningful premiums over raw. 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 22× — sealed copies trade at $229 while loose carts move around $10. That spread means a fresh sealed find is the move; raw cart flips have thinner margins after grading fees.

Frequently Asked Questions

Is George Foreman’s KO Boxing Nintendo NES worth grading?

Mostly for sealed copies. The sealed-state population (14) outweighs CIB and loose for George Foreman’s KO Boxing, 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 George Foreman’s KO Boxing?

PSA tracks 14 graded sealed copies of George Foreman’s KO Boxing 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 George Foreman’s KO Boxing?

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 George Foreman’s KO Boxing?

PSA’s database currently shows one tracked variant for George Foreman’s KO Boxing 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.
