Yeah, it's not grease or glue on the coin. The metal is pushed back toward the lettering resulting in a trough between the lettering and the rim below the surface of the coin. Maybe just an irregular struck though or defective planchette. I have another state quarter (Virginia) with the same error.
Thanks everyone for all their input. Much appreciated!
Wondering what type of error this would be? I can't find a similar example to tie it to. Is this just struck through grease that is causing the metal flow to be pushed back toward the lettering?

Thanks for the info. Do you know where I could find a reference to a Die event due to worn anvil? I couldn't find anything on error-ref.com. What's the main differences or key indicators between the die event and the spitting horse error? Again thanks everyone for all the feedback.
I found a spitting horse die crack Delaware state quarter. However, it's on a Denver minted quarter. I can't find any other examples, just the more common Philadelphia errors. The die crack is in the same position as the Philadelphia examples. Has anyone saw a 1999D spitting horse?
