All 2 PSA-tracked variants share the same PriceCharting prices because PriceCharting indexes at the title level, not the variant level. Variant-specific pricing surfaces on eBay sold-comp data — check the Sealed / CIB / Loose browse links below for variant-aware market signals.
Heritage Graded Sales
Heritage Auctions sold results below are real auction transactions for Mega Man & Bass 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.
The first table sums up this game’s Heritage sales by format. The sale records keep Heritage’s own variant notes, because a lot listing doesn’t always say which PSA variant it is.
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 | VGA 90+ | Last sale $450 | Jul 10, 2025 | 1 |
