Hi all,
I've been looking through a few Belgian 20 Frank coins, and have questions. Coins concerned:
These are all ok for diameter and seem roughly ok on weight (between 10.9 grams and 11.0x grams on scales which I wouldn't trust 100% on the decimals)




First question on the edge inscription:

Coins should be in the same order, note the jump in the text on the first one and second to last. I mistrust the first one already in general from its feel, and would take this as additional indication of potential fake. However the second to last one seems otherwise ok to me. Is this something that just happens?
Now the more confusing part, I notice that on quite a few of these (and not necessarily the ones I suspect of potentially being fake) there is a difference in the tilt of the ‘Fr.’ inscription. I hope these pictures clarify what I mean, the first should just alternate between the versions:

and a simple overlay maybe makes it clearer that the difference is pretty limited to the FR. and somewhat the date.

My basic question then: what am I looking at here? I can't seem to find anything about this as a variation, and if they indeed are fakes, to my eye they'd be pretty good. Or just nothing so see here, move on?
Penny (or centime) for your thoughts and best wishes,
