I have my own sets, usually:
GIL:USD
15:1 - Ul'dah and Ishgard
10:1 - Limsa Lominsa, Gridania
8:1- Smaller Towns/Outposts:
5:1 - Lower/Other: Things beggars and wandering travelers may expect, basic interactions in smaller venues outside of cities and towns.
Various reasoning behind them all, but that's sort of my guide. It's kind of a to each their own situation but I feel like most people are on a similar wavelength from my interactions.
