Roman state sets monetary policy and oversees the unit; physical production involves Rome / imperial mints. No. Tool-Lifes /money is a static educational atlas. It explains regimes, history and design without live tickers.

Why does Roman denarius matter globally? Global importance comes from trade invoicing, reserve holdings, financial contracts and migrant remittances — measured here as relative scores, not prices. What does the reserve-weight score mean? It ranks how heavily central banks and global finance rely on this unit compared with others in the atlas — an editorial 0–100 score.
