The 1999 Stadium Club Triumvirate Mark McGwire Illuminator #T5C is a Baseball card (Illuminator parallel) released in 1999. Ungraded copies carry a market value of about $58.66.
An ungraded copy is worth around $58.66, a PSA 9 around $58.77, a PSA 10 (Gem Mint) around $128.88 and a pristine BGS 10 around $168.00. The gem-mint premium is modest (about 2.2× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $58.66 and top grades reaching $128.88, 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.
