Couldn't find a match on VV it doesn't look like MD or DDD but the gunk makes it hard to tell. Didn't want to mess with the coin without opinions to do so.
I only see one Class V doubling and it seems to pivot on the west side of the coin and manifest in the FIVE CENT and MONTICELLO going east on the coin. Can you get clearer photos and photos of the full reverse? Not giving up yet.
I think we are looking at DDD. I notice that the lettering is thicker toward the rim which is a good indicator of die attrition and uneven surfaces. The D in UNITED was what had me wondering a bit since it looked a bit like Class V pivoting, but probably related to the ooze going on with the devices towards the rim. MONTICELLO and FIVE CENTS looks normal (although heavily worn in the center). I think it is safe for a soak in distilled and/or acetone to loosen up the gunk to see if there is anything we are missing.
