I bought this coin (Trier RIC 53) a few weeks ago. It's from a small issue from Trier, T/F//PTR. Although the MARTI CONSERVATORI reveres is quite common, I think the depiction of Mars is quite distinct from other series. In RIC the serie was rare enough to have two pictures on plate 3. I always enjoy these niche coins as auctions aren't going very well for me lately.
