Thank you very much for your opinions.
The two first images are of course the same coin (in the different light).
Well, we are working only with photographs. It's impossible to say if they were taken in exact the same conditions, but I have made a crude little experiment. I think it was worth a try.
In my opinion these are exactly the same angles, the distances between the columns and their arrangement (on the
reverse).
Also the letters have mostly exactly the same form and tilt (
obverse and
reverse) and there are some identical details. I don't think it's just pure coincidence.
