AI Appraisal Estimate

This is an original Super Nintendo Entertainment System (SNES) game cartridge for 'Super Mario World,' released in North America circa 1991. The cartridge is constructed of molded matte gray plastic with a rectangular shape featuring notched corners and horizontal grooves characteristic of the SNES NTSC design. The front label is primarily black with a central illustration of Mario riding Yoshi against a blue background, featuring the 'Official Nintendo Seal of Quality' and the 'SNS-MW-USA-1' identification code indicating it was made in Japan. The cartridge shows significant signs of age and use; there is visible surface grittiness, dust accumulation in the crevices, and a notable brown staining or residue on the bottom left corner of the inset face. The label appears mostly intact but demonstrates minor scuffing and edge wear. The security bit screws at the bottom are present, suggesting the internal PCB remains secured. This item represents a foundational title for the 16-bit era of gaming and serves as a classic example of early 90s console software manufacturing.

I have conducted a visual examination of the provided Super Mario World SNES cartridge (SNS-MW-USA-1). Based on the label architecture, font weight, and the presence of the original security bit screws, the item appears to be an authentic North American retail version produced in Japan. However, the physical condition is noticeably degraded. Significant brown staining/residue on the bottom left corner and accumulated grittiness suggest improper storage and exposure to environmental contaminants which may have affected the interior PCB. Super Mario World is a masterwork of game design but is extremely common, with over 20 million copies produced as it was the standard pack-in title for the console. In the current market, collectors prioritize 'mint' or 'CIB' (complete in box) copies. Loose cartridges are abundant and valued strictly as player-grade copies. Comparable sales for labels in cleaner condition typically reach $20-$30, but the visible surface damage on this specimen places it in the lower tier of the market. A definitive valuation is limited by the inability to inspect the connector pins for corrosion or to open the shell to verify the internal board components for repairs or soldering issues. A full authentication would require an in-person continuity test of the chip and a physical check of the 'Made in Japan' stamp on the rear label. Without a test, this is valued as an 'as-is' collectible with high utility but low rarity.
