I have just bought this coin of Claudius II
D/ IMP C CLAVDIVS AVG
R/ FIDES EXERCITI, no mintmark
It seems to be a 1st issue from Rome mint probably from 11 officina as the common short type legend reverse "FIDES EXERCI" listed at n. 274 of new RIC http://www.ric.mom.fr/en/coin/274?q=274&page=1&mod=result&x=0&y=0&from=quick
Is it actually a new type or did I get my search wrong?
