In the perfect world the die axis would either be medal (both sides upright) or coinage (upright points to opposite end on the reverse and obverse, like in US coinage). (Actually I disklike coinage die axis, and in the perfect world only medal die axis would exist :p ) I know for Canadian coins the rotated axis less than 15º has not much numismatic value.
