The balneum of the Roman villa of Vilauba was excavated in 2014. The archaeological site is located in the northeast of the ancient Roman province of Hispania Tarraconensis, now in the municipality of Camós (province of Girona, Catalonia, Spain). In the west part of the thermal complex, which was built during the second half of the 2nd century AD, a small room was identified as a latrina, crossed by a water evacuation channel built of tegulae. Found over the tegulae was a group of forty coins. Mostly AE4, the coins were dated to the second half of the 4th century AD.
In the present paper we analyse in detail the composition of this fairly uniform group of coins, and address also some other problems, such as chronology, the value of this group and possible reasons for its concealment.
