I think that second picture IS the other side.
I also think that it is not VI but IA as rotating the image there looks
like an exergue line on it, making it IA (maybe). Such as on the end
of the UK old 1 Penny coins (34mm) with BRITANNIA design.

On the first side there seems also to be some lines.
That was just a quick guess, but still could be some other coin,
or other lettering.
