What's the difference between these two that they have to be assigned with different KM number?

KM#40a.2 (medal alignment; edge inscription embossed)
KM#40a.4 (medal alignment; edge inscription embossed)

KM# 40a.1 is coin alignment with edge lettering embossed (raised), KM# 40a.2 is medal alignment with edge lettering embossed, KM# 40a.3 is medal alignment with edge lettering incuse, and so on. As described to the right of each year.

Hi Tony,

I understand about the difference of the three. I just don't get it why there's 'a.2' and 'a.4' if they have the same features.

Hello

The only different i know between 40a.2 and 40a.4 is the mintmark.

40a.2 without mintmark
40a.4 with mintmark "B"
