An error where the photographic image is flipped horizontally (mirror image). The most famous examples are the 1989 Upper Deck Dale Murphy and the 1957 Topps Hank Aaron.

Condition & Grading Challenges

Verification Essential: Errors must be cross-referenced with known population reports. Many 'errors' are simply one-off printer scraps (freak defects) rather than cataloged variations.

Investment Profile

Niche Market: Errors have a highly dedicated but smaller buyer pool. Liquidity can be lower, but 'famous' errors (like the NNOF) command astronomical premiums.
