Just like buses, nice coins often come in pairs - unfortunately in this case I didn't catch the second one! In the recent VCoins auction, lot #53 was a coin of Licinius I with the unknown, for London, obverse legend IMP LICINIUS AVG. The title of this post links to the auction record. It seems to be from the second T/F//PLN issue again and would sit between RIC 98 and 99. This obverse legend does occur at Lyons and Trier at around the same time, but is rare at those mints.
