i have a 1970 S penny with no FG initial printed on it I even use a microscope to double check. Is it possible?
Show the entire Reverse please. Could be an over polished die issue but only by looking at the entire reverse can we tell.
Its there Mai...just greased and worn. Sometimes a camera programs will give a bad result...especially when taking a digital picture of a digital screen. Try to take a direct photo of the coin capturing the entire side.
