At the FUN Show, I saw more than one PCGS
"error" coin on display by dealers. One was a 1909-S Indian cent with a 1909-S Lincoln tag. Another was a 1918 Lincoln commemorative half, labeled as a "so-called half" - not even a coin. If the top TPG
business can make such gross attributions, just think about what they can do to a numerical grade. The difference for a slabbed MS-66 Buffalo nickel, were it labeled MS-67, exceeds $30,000!
