I wondered that too. Next to the VF Red seal, it looks lighter, but it looks fine to me under a microscope for the amount of wear it has.
Wouldn't it be hard to wash the black away without effecting the Gold?
Also, don't know of any other note with that configuration of Gold ink on the seal and the serial.
1928 Gold Certs have seals on the left, North Africa Notes have blue serials, and much larger seals.
