A decent sword was about a two month’s wages for the average medieval peasant. Generally in medieval armies, only the King, his personal guard, and vassal Lords had a full set of weapons and armour - everyone else had to make do with a thick cloth or leather coat, and whatever weapon they could scrounge from the farm and/or get hastily modified by a blacksmith. The PC is a blacksmith though, so he should be able to make a decent weapon and decent armour for a reasonable amount. Not saying it should be cheap, but he shouldn’t be able to get much change from a florin for a mail coif. (Mail coif = hood made of chainmail. Florin = gold coin worth 20 Groschen or 240 Pfennigs. Daily wage for a skilled worker = about 10 Pfennigs)
