2012 Topps Allen & Ginter George Brett Mini #137 value & prices

The 2012 Topps Allen & Ginter George Brett Mini #137 is a Baseball card (Mini parallel) released in 2012. Ungraded copies carry a market value of about $1.69.

An ungraded copy is worth around $1.69, a PSA 10 (Gem Mint) around $128.00 and a pristine BGS 10 around $166.00. That's roughly a 76× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.

Is it worth grading?

With raw copies near $1.69 and top grades reaching $128.00, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
