English Jetton

Just been given this Jetton, -English,13th,14th cent. One side is plain, - a cross (fleury ?) but I can't make out what on earth is on the other side. There is a very good site:- http://www.mernick.org.uk/englishjettons/catalogue.htm
but I need to identify the obverse(?) reverse(?) of the cross. Any help appreciated! Weight 2.02g diameter 20mm

Not sure if it is English - looks more French to me.
Triple cross fleuretty I have seen before somewhere.
And yes no idea what is on the other side yet.

Thanks Zac. I did read that English jetons had a hole in the middle, whereas French didn't, but perhaps that's not so.
