Japan 1922-1937 Mt Fuji and Deer old die vs new die - help

I have some of these. Are there any other differences between the old die and the new die other than the size of the design?

(19 x 22.5 mm for the old die and 18.5 x 22mm for the new die)

I'd like to make sure I get the ones I have assigned the correct Scott #. For example 172 vs 172a.

I see there is quite a bit of difference in Scott catalog value between old and new die varieties.

Thanks...
