I have a 1978 dime with no D or P above or below the year, but kind of diagonal on the right side in very very small print, i cannot tell if it's a 0 or what else it is and it also either has a S or a 5. I also have two penny's with no D or P on them and the years are: 1983 and 1978 are these coins possibly worth anything, they are all in pretty good condition thanks for helping me if you can on my 1978 penny there are no bullets on neither side of the word "UNUM" and also when you rub your finger across both sides of the penny, it feels like there i nothing there, and on the back where abraham lincoln is sitting it just looks like a smudge and not him sitting there
The two cents(we're not British) are worth just that, 2¢. Give or take a few cents for copper value. Coins with no mint mark were minted in Philly.
The dime I'm not too certain about. Without a picture I can't say for sure. Maybe someone else lurking knows?
Cents with no minmark are Philly. Dimes, starting in 1980 (? don't qoute me on this though) used a P for Philly, so your 78 without a mintmark is normal.
