Ethiopia, 25 santeem 1944

Ethiopia, 25 santeem 1944 (https://en.numista.com/catalogue/pieces4391.html):



Olé, here is a third one, also with the crude edge:

As you can see, the last digit of the date is right in the middle of two scallops, the first digit is even on the left side of a scallop (in both your cases it was on the right side of a scallop) and the third digit is right on a scallop (in both your cases it was in the middle of two scallops).

Verweis : "Essor Prof"​Olé, here is a third one, also with the crude edge:

I think I read somewhere that the regular round 25 santeem KM#35 was at a later moment scalloped into KM#36.

So scalloping was done after minting, and apparently, the orientation of scallopes with respect to legend is random.

For comparison my coin at the bottom (which has crude edge):

Verweis : "ArnoV"​​So scalloping was done after minting, and apparently, the orientation of scallopes with respect to legend is random.

​Yours is the third example of a crude edge with different orientation scallops/legend. So you might be right the orientation is random, at least for the type with the crude edges. I have 7 coins with a fine edge, and with all 7 the orientation scallops/legend is identical. That can't be a coincidence, if the orientation really would be random, it's impossible to have 7 identical, and not any other.

NGC-coins has the following note for the round KM#35:

Verweis 421,500 issued and 1952 withdrawn and replaced by KM#36

And the following for KM#36:

Verweis Issued in 1952 and 1953. Crude and refined edges

Perhaps the variant with crude edge and random scallope orientation is a refactored KM#35, while the variant with fine edge and fixed scallope orientation was newly minted KM#36 in 1952-53.

I have acquired my coin in the mid 1970-ies.

​Yes, I also think it's something like that.
