Anyone any good with cut halfpennies??

Hi, I'd really appreciate some help with the attached if at all possible.

I think I can make out the H for HENRICVS on the obverse, so I'm thinking Henry III longcross???

The reverse looks a bit weird - double struck maybe?

If any one can help with confirming its ID that would be great. Anything else including class, mint etc would be a bonus! 

Many thanks in advance

James
