Quite a nice find, this. Or it is to me, anyway. I believe the obv is [henric]US REX III.
As for the rev...well...it appears to end either ILV or TLV. Would this be 'LV' as in 'LVND'? If so, I'm having trouble working out the name of the moneyer.
And if anyone had any ideas as to the class, well, that'd be pretty amazing!
