money attribute nothing special

Prefix the number with - (hyphen).

And if URp saves a string that begins w zero it will remove the leading zero. So I have to remember to force save that before leaving a form.

Only if the attribute doesn't already exist for that item, and the formatted display of a Money attribute will truncate leading zeroes anyway.

Are there any other rules I should be aware of?

Not that I can think of, but if there are, I'm sure you'll find them :^).
