My face to face group would riot if I tried to make them do all their shopping in pounds-shilling-pence-and-all-that-other-stuff. Riot, I tell you. I don't think either of my online groups would be thrilled either.

They're fine with being told that the treasure is "30 copper, 10 silver, and 4 quarter-gold", but that's like telling them it's "Two 10 ct spineals and a 2 ct ruby", it's a nice-to-know, but what they really need-to-know is value (for vendoring) and weight (for encumbrance until they vendor the loot).

I'd get (slightly) more traction asking them to shop in some sort of hexadecimal system; at least there's lots of calculators that support hex notation.
