The 1998 Stadium Club Triumvirate Ken Griffey Jr. Illuminator #T3C is a Baseball card (Illuminator parallel) released in 1998. Ungraded copies carry a market value of about $227.50.
An ungraded copy is worth around $227.50, a PSA 9 around $300.00, a PSA 10 (Gem Mint) around $338.00 and a pristine BGS 10 around $439.00. The gem-mint premium is modest (about 1.5× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $227.50 and top grades reaching $338.00, 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.
