| Is that 2,000 coppers in your pocket or are you just happy to see me? |
From page 92 of the 1st Edition AD&D Dungeon Master's Guide:
Electrum will be most unusual, gold rare, and scarcer still will be a platinum piece or a small gem! Rarest of all, treasure of treasures- the magic item - is detailed hereafter (PLACEMENT OF MAGIC ITEMS). If some group of creatures actually has a treasure of 11 gold pieces, another will have 2,000 coppers and yet a third nothing save a few rusty weapons. Of course, all treasure is not in precious metals or rare or finely made substances. Is not a suit of armor of great value? What of a supply of oil? a vial of holy water? weapons? provisions? animals? The upper levels of a dungeon need not be stuffed like a piggy bank to provide meaningful treasures to the clever player character.Now if only I could find a reference to nine giant rats in the 1e DMG my quest would be complete...
