As vintage card values skyrocket, the temptation to artificially enhance a card's appearance grows more sophisticated. Inpainting involves using specialized inks or markers to hide edge wear and corner touches on classic cards from the 1950s and 60s. These alterations are designed to fool casual observers, but they fundamentally change the chemistry of the card. Professional authentication acts as the frontline defense against these deceptive practices.

Lighting the Path to Truth

We utilize short-wave and long-wave ultraviolet light to expose foreign substances on the card's surface. Original factory inks and paper stocks have specific fluorescent signatures that are nearly impossible to replicate with modern markers. When exposed to UV, restored areas often glow with a different intensity or color, immediately flagging the card as altered. This non-destructive testing is vital for maintaining the integrity of the vintage market.

The Impact of Chemical Cleaning

Beyond adding color, some attempt to remove stains or wax marks using solvents that strip the original surface gloss. Our labs look for the tell-tale signs of chemical residue and disrupted paper fibers that indicate a card has been washed. A card that has been chemically treated is no longer in its original state and must be labeled as such. Authenticators serve as the historians of the hobby, ensuring that original condition remains the standard.
