Are baseball cards still authentic if they have been restored?
A number of high-end baseball cards have been restored to Mint or close to Mint condition. Many cards are restored to high grade by adding vintage paper and toxic chemicals to restore the worn corners, and sometimes by inpainting. As with reprints, there is nothing inherently wrong with restored cards so long as they are clearly represented as such. Restorations can often be identified by a visual inspection. Some inspections involve a black light test which can be less than effective if the colors are dark.
