The rules for series dates and letters are different from what they used to be. There's more information at the Related Question link below.
The letters under the dates on Lincoln cents are mint marks and can only be a D or S and are used to identify which mint made the coin. D is for Denver, S is for San Francisco. Also coins with no mint mark means it was made in Philadelphia.
Dates of attendance are dates you have been given for something like classes or hospital appointments and they register which days you attended, giving them your dates of attendance.
You have what's called a filled-die error. That error occurs when a bit of grease or other crud gets into one of the small recesses of a coin die that forms the letters and numbers when it strikes a coin blank. Coins are minted by the millions at very high speeds so filled dies happen fairly often. There are "niche" collectors who will pay small premiums for filled-die coins but in general they're only worth a small amount above their face value. For what it's worth, dates have numbers in them, not letters, LOL!
Yes they did have dates, but they were all written in Roman numerals. yes they ate them all the time!!!!!
They do - the dates are in Hebrew letters.
