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.

It's even possible to learn it.
I've even done a little two-digit multiplication! ...Didn't get over B * B.
And, seriously, it has some major advantages over decimal.
10, 8, 4, 2, 1, 0.8, 0.4, 0.2, 0.1, 0.08...
10, 4, 2, and yeah it gets hairy after that, but 1.66274 is not any harder to remember than 1.41421.
OTOH, 10, 5, 2.5, 1.25, 0.625, 0.3125, 15625...
Or 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024...
Compare to: 1, 2, 4, 8, 10, 20, 40, 80, 100, 200, 400, 800, 1000...
The rest is number sense. And barring missing digits, you can count it on all fingers and both thumbs, which is important for early learning. First thumb, 1, 2, 3, 4, 5, 6, 7, 8, second thumb, 9, A, B, C, D, E, F, 10. Gets you six more digits than just linear counting on your digits.
