Denarus Coin (IMAGE) Goldschmidt Conference Caption The coin in the photo is a denarius, minted by Rome between 108 and 107 BCE. The three red marks denote the sampling locations, where the coin has been drilled at its rim to obtain fresh, unweathered heart metal for the measurements. Analyses indicate that the silver the coin is made of originates from mining districts in the southeastern part of Spain.
