Code:
return calc.."|TInterface\\MoneyFrame\\UI-GoldIcon:0:0:2:0|t "..silver.."|TInterface\\MoneyFrame\\UI-SilverIcon:0:0:2:0|t "..copper.."|TInterface\\MoneyFrame\\UI-CopperIcon:0:0:2:0|t"
That's inserting the standard coins into a string using |T |t (texture) start/end escape sequences.
For more information on escape sequences,
