1964 D dime-partial letter missing, first post

[STARlight]

Hi, I'm wondering if anyone has ever come across US coins with missing letters? I have a 1964 D Roosevelt dime, on the reverse or back side of the coin part of the "O" in One is missing. I first thought it might be a die crack or a filled die, just want to know a little more from the pros. Thanks!

It appears to be post-strike damage.

Welcome to the forum! We are glad to have you here.

I've also seen dimes with ejection doubling that shave off part of a letter. This could be responsible for what you see on your dime. When I was a rookie, I found this one in a 1963 proof set...

I thought I really found something - a Doubled Die (but was wrong). It is interesting - but not worth much.

So, is that what it's called ejection doubling.? I just thought It looked a bit odd and wanted an expert opinion....Thanks much for your help.:)

What is a post strike damage? Sorry I'm a newbie, does this happen after the minting process? Could you explain a little better?:confused:

Strike doubling, ejection doubling, mechanical doubling, etc. are all terms to describe a doubled look that appears on a coin that is not the result of a doubled die. In other words, the doubling is not on the die (the die has the normal image of the coin elements) -- but the doubled look occurs for various reasons just after a coin is struck. It is usually the result of a loose or chattering die. Extreme examples may carry a small premium -- but this form of doubling is pretty common and is often confused with true doubled dies (which can be very valuable).

As I said - I can't be sure from your photo exactly what caused that "O" to be shaved off. I added my photos because they show a similar "post strike" result. For reference, here is Ken Potters page that shows different types of doubling...

Hopefully this will help you learn what these hobby terms mean.
