Hi,, According to Numista This coin has 2 varieties https://en.numista.com/catalogue/pieces6962.html One with a hole in the heart above the lion in the middle. I think this coin is that particular variety - but am not 100% sure.
Not sure which one you have - Numista mentions three variants exist: 1: Normal heart above the lion in the middle 2: Hole in the heart above the lion in the middle 3: Hole in the heart [above the lion in the middle] and "double struck" (or "double die") of the heart and the bottom crown
I just located all 3 varieties on Ebay. Link: https://www.ebay.com/itm/224350745640?hash=item343c58b428:g:y0sAAOSwvBhho5Lx
Your photo looks like variety #3 on these pics I posted above. #3 variety from @BasSWarwick list from post #2 above.
I have the first two in my collection. 1: Normal heart above the lion in the middle 2: Hole in the heart above the lion in the middle I have never seen the doubled die with the hole in the heart. Yours sure looks like the doubled die with the hole in the heart, can you take a closeup photo of the coat of arms?
