Not a proof, all proofs are S mints. Those bumps are zinc rot. Your pix actually captured it well although a bit blurry. Note the disturbed area surrounding the "bump" under date. There's a growing colony is rot under there. It seems same w/ NE lump also, if its a bump, otherwise is an old "milkspot" from the crappy mint rinse.
You're not even getting "the finger" on that one!
That's the DDR
