A good rule of thumb for roleplaying is $1000 per troy ounce (approx 31 grams). There are many coins that are about an ounce size so this is a useful approximation. Now this is actually a useful currency for a group of heavily armed mercenaries who buy ammunition, fuel, weapons, and manufactured goods in bulk, like say PCs. But not common people.
So no chests full of gold, but briefcases would work.
