Lincoln memerial cent 1969 s  see pictures: UNITED Letter "E" Faulty coins are rare (and some exceptional) because the minting workshops carry out regular checks to verify the quality of the coins produced, and therefore anomalies are quickly detected and corrected, and the faulty coins are scrapped for destruction... however some manage to pass these checks... (production error + inattention during checks = RARE)
