Pictured here are the debased coins of Gallienus. Most of these once silver coins are not merely reduced in weight, but are struck in bronze and are generally of a very poor quality with respect to workmanship, style, weight, and regularity. Precisely as the USA and all countries did in 1965, the Romans also removed silver from the coinage, but in modern times we replaced it with a white meal (nickel) to give the appearance of silver. The Romans pulled a similar trick. They issued the coins in bronze, and then silver plated them to make them appear to be silver. Such coins that survive with the silver plating intact are naturally much more difficult to find. The silver plating wore off quickly, and any hoard coins that are cleaned that had the silver still present, end up removing the silver to get rid of the corrosion. Pictured to left, are four coins with much of the silver plating intact, but as often the case, they are badly corroded. Bronze does not survive well in the ground. Consequently, finding acceptable specimens with the silver intact is very difficult.
