The 1999 Stadium Club Triumvirate Ken Griffey Jr. Illuminator #T13B is a Baseball card (Illuminator parallel) released in 1999. Ungraded copies carry a market value of about $407.70.
An ungraded copy is worth around $407.70, a PSA 9 around $300.25, a PSA 10 (Gem Mint) around $565.01 and a pristine BGS 10 around $735.00. The gem-mint premium is modest (about 1.4× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $407.70 and top grades reaching $565.01, 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.
