Field notes
The project treats the denarius as both an object and an evidence trail, combining a historical essay with sections for sales, museum holdings, market availability, and counterfeit examples. It identifies the issue as Crawford 508/3 from 42 BC and reports approximately 90 documented specimens, including about 21 in museums. The page also estimates that 30–40 can be bought, while only 1–2 reach the market in a typical year.
