I don't have a coin of Mithradates II, so here is a Parthian tetradrachm of Vardanes I which I won last night. I'll have to get the exact attribution confirmed, most of the description was in Japanese Vardanes I 55-58 AD AR Tetradrachm 14.04g
I only have a couple Parthians, and I could see getting addicted to them easily...I like this guy with the 'Royal Wart' on his forehead. Orodes II
