Have one I have had since about 1955.
The mint did not make a mistake and forget the date on the die.
If they would have there would be many other examples.
That leaves 2 options
1) Grease filled die
2) Altered coin (date removed)
If you can see no damage, then it's likely from a grease filled die. Interesting but won't pay off your car.
Grease filled die: Dies are stored on shelves for future use. Because the Mints were damp from all the wood heating, metal melting, etc, they covered the dies with grease to stop rust from forming. When a die was needed they took one off a shelf and wipe the grease from it and began using. Sometimes a bit of grease was left in the crevices of the die (not completely cleaned off). Then when used the coins did not get fully struck up with details missing as the metal could not flow into the die due to the grease being there already.
hope that helps.
Certainly not rare or even scarce. Not much value. A couple of bucks, maybe to the right buyer. Not much demand for such 'errors".
Did you not get the answer you wanted when you posted this in the Q&A forum on the 29th?
not really, a possible grease die error, whatever that is. Was wondering if it was really something or a mint error, and possible value.
TAKE A PIC and post it here. That way we can see and help.
This is as good a pic as I can do, with a magnifying glass I can not see any sign of a removal.
Not sure my files were on the last post, will try again.
So is there any value at all other than one cent/
Thanks for all of your inputs!
I would guess if you listed it at 99 cents start on ebay it would end between $5-$25 but you never know.
Thanks, thought I had something all these years (from around 1955). lol
