I have always thought the single squeeze for the ONE CENT began in 1998... I think I am wrong... According to an article by Ken Potter for CONECA https://conecaonline.org/so-just-whe...hubbing-begin/ the pilot program began in 1986 for the working dies and was already in use for the master dies and working hubs... So did we see our first single squeezed Lincolns on the 1986 or 1987 coins???
