Description: | Roman copper-alloy nummus of Constantine I dating to the period AD 308 to 309 (Reece period 15). PRINCIPI- IV-VENTIVS Prince standing facing, head left in military dress, holding standard in each hand. Minted at Lyon. RIC VI p.264, no.299.The coin has a patch of silver metal visible at 4 o'clock on the obverse. Nummi of this period were agentiferous copper alloy, ie they contained a small content of silver (decreasing from 4% in AD 307 to 1.5% in AD 310). The patch is presuambly a patch of higher silver content metal due to incomplete mixing of the molten metal prior to production of the blanks.Various cracks in the obverse die, which must have be near to the end of its use, are visible as raised lines.The combination of these two flaws in production are probably a reflection of the inevitable mistakes made with high volume production.
