2020 Donruss Joe Mixon Press Proof Gold Game-Used Ball Relic Card #77/145

This is a 2020 Donruss NFL trading card featuring Cincinnati Bengals running back Joe Mixon. The card is a limited edition 'Press Proof' parallel, specifically serial-numbered 77/145 as indicated by the red foil stamping on the left edge. A significant feature of this card is the circular 'Game-Used Ball' relic window, which contains an authentic piece of leather from a football utilized in a game. The right side of the card specifies '12/1/24 JAX vs HOU', indicating the source of the memorabilia. The card features a vibrant gold foil finish with holographic light-refracting properties across the background. The player is depicted in his Cincinnati Bengals home uniform in a dynamic action pose. It is currently housed in a professional magnetic 'one-touch' hard plastic case, which is further protected by a clear poly sleeve. The corners appear sharp through the casing, and the centering seems consistent with late-modern Panini manufacturing standards. The surface shows high-gloss finishing with no visible scratches or print lines from this angle. The 'Donruss' brand logo is clearly visible in the upper left corner, confirming the manufacturer as Panini America.

I have examined the digital representation of this 2020 Donruss Joe Mixon Press Proof Gold Game-Used Ball Relic. The card presents in 'Near Mint-Mint' raw condition, with sharp corners and no visible surface abrasions through the one-touch case. The serial numbering (77/145) provides a specific layer of scarcity common in the Panini Donruss product line. Joe Mixon remains a productive veteran, but as a non-rookie relic card, the value is driven more by the novelty of the game-used football swatch than by long-term investment speculation. The 12/1/24 date mentioned appears to refer to the specific provenance of the ball relic, which adds a layer of 'player-worn/game-used' authenticity that collectors value over generic 'event-worn' materials. Market comparables for mid-tier veteran relics from Donruss typically trade in the $30-$75 range depending on the specific parallel and serial numbering. The 'Press Proof Gold' finish is desirable, though not as liquid as 'Optic' or 'Prizm' equivalents. The greatest limitation to this appraisal is the inability to verify the authenticity of the relic swatch through the casing; I cannot inspect the edge of the window for 'faking' or ensure the surface high-gloss isn't hiding micro-scratches. Full authentication would require a physical examination under 10x magnification to confirm the red foil stamp impressions and the leather grain of the football. Furthermore, a professional grade from companies like PSA or BGS would be required to reach the upper end of the valuation spectrum.
