Unfamiliar attribution on an NGC slab for a Barber dime

Casey

I have an 1893 S/S dime in AU50. The slab indicates "FS-009". Does anyone know what that refers to?

Thanks,

I'm guessing that means it's the S/S variety in the CP guide.

They should be using Lawrence designations for Barber varieties since he wrote the book.

Yust my opinion.
