Need Help Understanding The Value Increase Of Missing Letter Errors

Would have to see pictures. The R could be missing for any reason from post mint damage, to a Struck Through Grease, to a more major strike through, a lamination, or possibly something else entirely. I would say most likely no increase in value unless it's a major strike through, lamination, or something else fairly significant.

@nj, first welcome to CCF. Second, while I agree with everything that @sc said, I note that even if the missing letter is from grease, that isn't enough of the design missing to really affect the value. Usually, more of the design elements (think whole words) need to be missing before you get much of a bump in price due to a grease-filled die.

Good point @SC. Now that I re-read your original post, I actually agree with everything you said.

to the CCF!

Usually a missing letter or number are not actually missing. most times you can actually see the missing letter or number using a scope or magnifying glass or even turning the coin a certain way. This is usually due to the reasons listed above or highly polished die. Depending on what the cause of the missing letter or number will determine the value.If you post a picture we might be able to at least point you in the right direction if not give you a definitive answer.

Lol. Wrinkled fender. I think that's (one) of the reasons my wife wants to turn me in for a new model.
