Hi all, just spent way too much of my money at the local coin show. The following piece was one of the more expensive pieces I bought.

Antioch (Syria), silver/billon tetradrachm of Trajan Decius. Obverse: radiate bust right, AVT K G ME KV DEKIOC TRAIANOC CEB around, one pellet (?) below bust. Reverse: eagle standing right on palm branch, wreath in beak, DEMARCh EXOVCIAC around, SC below.
I really like this coin. It's got pitting issues, but unlike some of the Wildwinds examples, almost no die wear or wear from circulation.
I'm looking for assistance / confirmation of the attribution.
Wildwinds lists these coins of Antioch as "Prieur" numbers, with a wide selection of varieties which seem to be based on relatively small differences. Prieur 541 is the best match I can make from Wildwinds, but their list is not complete. Does anyone have a better suggestion, or another reference number I can label my coin with?
