History:
The coin described in the above named reference works (not the coin here on wildwinds) was or is part of the collection of the Museum of Lyons, France, formerly the collection at Trinity College, Lyons. A catalog of the coins in the collection was compiled in the 1700s but many of the gold and silver coins were stolen from the Lyons town hall and/or melted down during the Napoleonic period by a gang of five led by a certain Amiot. 

In 1793 the old, delapidated museum sold off some gold and silver coins for their scrap value, (although it cannot be confirmed that the proceeds were used for the benefit of the community!.)
The bronze and most silver coins which had not been stolen or sold off were moved to the new museum in the early 1800s.
In 1880 a document from 1791 was discovered, which, according to the article in RBN 1881, "contains a certain number of gold coins which are not found in the work by Cohen..". 
Amongst these coins are three aurei of Vespasian: 
- COS III FORT RED, Fortuna (= RIC II 1110, citing Lyons)
- COS III TR POT, Aequitas, (not in RIC with the given legends)
- IVSTITIA AVG, (not in RIC), as this coin.
