Ancient coin help... Pics of unknowns..

I cannot find any info on these. Any help would greatly be appreciated. -Dan
This coin has the highest relief I think I have ever seen. What is the green stuff?


Probus?


It is Caeser and Marc Antony?

#2: Probus indeed. A base-silver (something like .050 fine, as indicated by the XXI in the exergue) antoninianus, reverse type SALVS AVG (health of the emperor), Salus standing feeding a serpent rising from an altar. Siscia mint, officina-mark delta (fourth). This particular type is listed in the millennium Sear, but I think it's genuine. Very similar to this one.
#3: It is indeed supposed to be a Caesar and Mark Antony coin, Sear #1465, but the colour and appearance of this one give it away as a tourist copy, also.

Apparently I have been awarded one DPOTD.
