follis 317-337 AD Interesting camp-gate error of Constantius II as Caesar , Siscia mint, Roman Empire - with "CAESAR" omitted

FL IVL CONSTANTIVS NOB, Laureate, draped and cuirassed bust left / PROVIDENTIAE CAESS, Camp-gate, DSIS"double crescent" in exergue. 19mm, 3.6 grams. Mint of Siscia, RIC 217.

Interesting engraver's error - the last letter "C" that is supposed to end the obverse inscription is missing - probably because the engraver overestimated the amount of space available for on obverse and ran out of space before the inscription was completely engraved. A neat piece, I've never seen this particular engraver's error.
