4 types of Roman terracotta paving stones from the thermal baths and Roman villas of the town "Viminacium" in the region formerly called Moesia (currently in Serbia). In the photos of the paving stones you will find an example photo of hexagonal paving stones from the thermal baths. The smaller 8-shaped ones are extremely rare.
See my other auctions of Roman coins, Aureus, Solidus, and others, if you buy several, can I make a price?
