Characters with this skill are used to handling coins from all parts of the world, having perhaps worked as traders or having had other close dealings with money. They are aware of all the different sorts of coin in common useage; know their origins, names, metal contents, and relative values; recognise which are most likely to be underweight, and so on. In the Old World there are many different currencies, issued by various states, individual cities, or trade guilds over the years. Some are more popular than others, but in all cases value is determined by the weight of the coin's silver or gold. Skilled characters can recognise forgeries or clipped coins at once and will always recognise the origin of unusual, foreign, or ancient money after a successful Int test.
