The 2012 Topps Allen & Ginter Michael Phelps Mini Allen & Ginter Back #129 is a Baseball card (Mini Allen & Ginter Back parallel) released in 2012. Ungraded copies carry a market value of about $4.98.

An ungraded copy is worth around $4.98, a PSA 10 (Gem Mint) around $39.85 and a pristine BGS 10 around $52.00. That's roughly a 8.0× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
