Here is my latest campgate addition. It is a hybrid (mule) with a Constantine I obverse mistakenly paired with a Caesar (CAES•) reverse. This is an official mint product versus unofficial. The unofficial coins often mix and match obverse and reverse; but this rarely happened at the official mints. The proper reverse would be PROVIDENTIAE AVGG. Constantine I A.D. 328- 329 18mm 3.0g CONSTAN-TINVS AVG; pearl diademed head right. PROVIDEN-TIAE CAES•; campgate, two turrets, no doors, star above. In ex. SMNS RIC VII Nicomedia 153/157-8 (for obv./rev.) https://constantinethegreatcoins.com/campgates/
