Maximinus II, Constantine II From the Dorney Auction last week, please view and comment. Ye old Mammothtooth
Decent coins (I like the portraits!) but if you want to make sure your attribution is correct (I do for my coins) pay attention at the subtle differences - they can be very subtle for LRBs. Constantine II - provided attribution is RIC VII Treveri 520. Actually it's 527 as your mintmark is TRP dot. 520 has simple TRP.
