I had a nice moment in my Porttown campaign where the party fought, in succession, a bunch of solid gold constructs and a basilisk, and came back to the dungeon with a bunch of hired sailors to cart out a bunch of gold and stone bodies! I thought about trying to calculate how many gold pieces you could make by melting down a Small humanoid figure and turning it into coins, but wound up fudging the numbers so that it came out to the amount the party would need to pay for a bunch of stone to flesh and still have enough left to catch up to their recommended GP value for their levels.
