For the last 6 months I've noticed a lot of Aulus Gabinius Tets on the market from most of the major auction houses & wonder if a hoard has recently been discovered ? The recent offering from Roma Numismatics, E-Auction 79 has 10 of these coins , see photos below of 3 of their coins. I bought the coin pictured below many years ago & paid a hefty price for it. Today you can score nice looking examples for a fraction of what I paid for this coin .
Your coin is the best of the best Al , hard to compare it with lesser quality coins. I paid 65 GBP for mine August 2020 , about very fine imho
If someone did find a nice hoard of Eid Mars denarii outside of Italy, there would be a fierce battle of different countries trying to claim it & the litigation could go on for years .
