It felt much better to slowly build up copper and silver for the 10-100 gold DAO items than it does to save up 10s and 100s of gp for 10000 gp. Past a certain point, getting larger numbers of gold just doesn't feel that impactful.

Doing something like this isn't really feasible for D&D 5e RAW since the denominations are only a factor of 10 apart instead of 100. But it'd be nice if BG3 changed/added denominations such that we were building up for tens or hundreds, maybe thousands at most, of the highest (platinum? titanium?) denomination by end game. Perhaps Larian could multiply the worth of money by 10 (making sp equivalent to what-is-now gp) and then make pp worth 100 gp? Levels 2-3 get bronze and silver. Level 4-6 begin to build up gp. Level 7+ start saving up that pp.
