The icon themes Breeze, Sifr, Elementary, and Colibre show a dollar sign as icon for the currency button. This is not appropriate to an international product and should get reconsidered.
I’d favor Eike’s suggestion of metaphor at bug 100849 comment 25 (banknote plus coin).
Absent an ability to stamp a locale appropriate currency symbol other than the "$" onto the button face--as was agreed to by UX/Design team--the currency icon from each theme need attention dropping the "$"--I would suggest rifs on the "note & coins" from Tango.
The "note & coins" in Tango is readable. But the stacked coins in Karasa Jaga are a little hard to read--hay bales?, no coins.
