1958-D Lincoln..I know you think you know what this is about, but Look!!

I realize that the "1" and "9" in the date are not the result of a double die, but my question is.... Check out the 1 in the date. What caused the "serif" on the back side of the top of the "1". And also, what caused it to become machine doubled? Any thoughts???

That "serif" looks like a die chip.

Would the die chip also form a "double" image?? Do die chips become fused to the die itself?

kranky

A "die chip" means a small piece of the die broke away, which leaves a void that fills with metal when the coin is struck (just like any of the design elements). So a blob of metal due to a die chip can show machine doubling.

Great explanation Kranky. I have a hard time with abstract thinking. I have to remember to think of the dies as a reverse image Duh!
