Just accidently bought this duplicate this morning. Maybe a sign of old age.
This is RIC VI 47b which was at the old ~6.5g (1/48 lb?) standard, before being reduced to 1/72 lb in the following issue (wreath+globe vs eagle+thunderbolt).
RIC lists this type as common, but I'm not so sure. Checking on Ancient Coin Search for "thessalonica jupiter" there's not a single specimen, but a good number of the SM.TS wreath+globe issue, and a whole bunch of the following TSA one. There's also a fair number of the aureus version of this type, but that maybe reflects the tendency for higher end coins in auctions rather than the relative scarcity of this type in gold vs bronze.
Oh well, now I have two. Hopefully that won't become three.
