For humans and demi-humans, money is just a medium of trade. Wealth is
measured in money, but money is not the be-all and end-all. Real wealth is magic, armor, land, castle, livestock, servants & slaves. Money is just a means to acquire wealth.
For humanoids and many monsters (such as dragons), money is an end in itself. These monsters don't seek money in order to get something else. They seek money simply for itself. They acquire treasure and hoard it. The idea of trading for what they need does not occur to them. They kill and rob for what they need.
It is the capture of these monster hoards that creates what Gygax calls the "inflationary economy" of AD&D. When strange adventurers come into town, it is assumed they are rich with gold. All tradesmen instantly mark up their prices when they realize they are dealing with an adventurer.
As an old school gamer, the values stated in the DMG 1e form the foundation of the money system.
