Previous BG games (and NWN games etc) also generally refrained from 'vendor trash' items like plates and milk jugs. These are the items that would benefit most from expanding the monetary system to include copper & silver, because as-is right now a large amount of the items you can pick up are valued at 1gp. Would be nice to see less compression in the prices in the game IMO.
And really, of all the traditions Larian has brought over to BG III from the older games, and all the things it hasn't....I have a hard time seeing 'BG I + II only used gold coins' as an unassailable sacred pillar of the OG saga.

BG1&2 using a purely-gold based economy with inflated prices isn't a good argument for BG3 doing the same. Tens of thousands of gp at level 4 is still an obscene amount of wealth, especially given our location in some fairly minor part of a forest 10 days travel from BG. Like, sure, there's a Zhent outpost and an Absolute base nearby, but you don't need to rob the Zhents to get that much money and the Absolute base is staffed with goblins so really shouldn't be overflowing with wealth.
