That's... really, really odd. It looks like there's also some weakness in the hair and ribbon at the back of the neck...?
Hey, wait a minute I have the same coin mine has a neck part that’s missing. He didn’t polish polish the coin because I have one. Does anyone know if it’s worth anything?
The posters above were talking about someone polishing the die, not the coin. The die strikes the planchet to press the design into it. If the Mint workers polish the die too heavily (perhaps to get rid of damage), the high points on the die get worn down. These correspond to low points on the coin. As a result, the low-relief features on the coin -- like that part of Washington's neck -- can fade or disappear entirely. That will be true for every coin struck by the over-polished die until they take it out of service. Welcome to CoinTalk!
