1st thing I noticed were the dimensions.
I don't have one that I particularly want to chop the corners off for now, but I have a ton of perf 11 Franklins to compare it with side by side, all of which measure at 18.5 x 22, except this one measuring at 19.1 x 21.5 .
I know that a rotary press should be longer on either dimension, so it can't be that.
But I read somewhere that according to the paper used, design elements may shrink (amongst other inconsistencies depending on the paper type).
So I compared the backs and found that rather than having a typical flat solid surface, it has a mesh weave similar to those of the American "Banknote" series.
I don't know what those numbers mean written on the back.. but does anybody have any ideas?
Let me know if you want any more pictures.
