I accidentally started collecting Tetrarchy antoniniani from Lugdunum because I had several listed on Vcoins; but they were not selling for what I thought they were worth. I don't actively look for them. but when I get one in a group of coins, I usually keep it. Here is my latest...a bit scarcer type for Galerius.
