Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for Knockout Kings 2000 on Nintendo 64. 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.

|---|---|---|---|---|
| Factory sealed | CGC 9.4 A+ | Last sale $150 | Aug 13, 2024 | 1 |
| Factory sealed | WATA 9.8 A+ | $456-$660 range | Jan 10, 2023 | 2 |

Why Knockout Kings 2000 Matters for Grading
With 36 PSA-graded copies on record, Knockout Kings 2000 sits in the mid-rarity tier for Nintendo 64 — graded copies surface periodically on eBay but command meaningful premiums over raw. The sealed condition dominates submissions (35 of 36, ~97%) — a strong signal that’s where most collector value sits for this title. Sealed copies trade at roughly 7× the loose price ($64 vs $8.95). Solid spread for grading speculation if you can source a clean sealed cart.
Frequently Asked Questions
Is Knockout Kings 2000 Nintendo 64 worth grading?
Mostly for sealed copies. The sealed-state population (35) outweighs CIB and loose for Knockout Kings 2000, 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 Knockout Kings 2000?
PSA tracks 35 graded sealed copies of Knockout Kings 2000 for Nintendo 64. 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 Knockout Kings 2000?
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 Knockout Kings 2000?
PSA’s database currently shows one tracked variant for Knockout Kings 2000 on Nintendo 64. 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.
