1964 Silver Proof Roosevelt dime with partial collar error and die fill error.

I got a 1964 Silver Proof Roosevelt dime with 60% of the coin, front and back, with this smooth railroad groove.

The B in Liberty looks like theres a issue with it connecting in the middle.

This coin is still in the mint package.

Can someone help me correctly identify these errors so I can get a baseline value and know what im talking about before sending it off for grading.

I appreciate it.

Don't bother. You have normal Proof coins in that time period. Here are ones from 1961, 1962 and 1963:

Thanks,but mine has a cavity, not just a small ledge…

Maybe your comparing a error to a error 🤷, I just know that its not common and ones you see like that, has been graded a a form of partial collar error.

Cause yes it suppose to be flat with a slight edge, but no cavity going a portion of the coin til it slopes back up to normal height.  And both sides too, exactly opposite of each other.

I see people selling ones like we all typically see, the ones that go like that for 10  to 15%, people call them railroad rims, but not usually to that degree. 

Thanks and good luck to you also

Mine are just an artifact of light reflections.
