Although this is not a CAM, my wife did find this interesting coin in the car on the floorboard. It appears to be doubled on date, "LIBERTY", particularly the Y for one. It also appears the same with i g w t as well as on the reverse : e pluribus unum. Check it out, let me know what you find. Still looking for my cam though. For some reason 1992 seems to be my favorite LMC. Thank you, and happy Hunting.
IMHO.. 1992 is a Copper plated Zinc Cent What you probably are seeing is DDD - Die Deterioration Doubling or MD - Machine Doubling.
