I don't know if age is really a good measure. Our own world has been using coins for thousands of years, but, those coins vary widely. A Spanish doubloon and a Roman (crap! I forgot the word) gold piece are nowhere near the same weight.
OTOH, getting into real world economics in D&D is just far more work than it's worth. After all, magic items aren't subject to inflation. Yes, it's more realistic, but, doing it right would not add a whole lot of fun to the game, IMO. In other words, would you're players really enjoy futzing about with exchange rates every time they enter a new town?
Heck, I don't enjoy it now in the real world.
