Double Mite from the Netherlands?

I'm trying to identify this coin found near the Norwich area of England.  It's not an English hammered coin and I was told it probably came from Europe.  It's approximately ¾" in diameter, wafer thin and copper or a copper allpy. After researching it several weeks I seem to have isolated that it probably came from the lower countries and was probably hammered in the mid to late 1300s.  Closest match I've found seems to suggest it may be a double mite of Lord Reinald II van Valkenberg of Born, Netherlands.  
The symbols on the back of the coin could possibly translate to “money of Reinald?”

I'd appreciate any information anyone could provide about this coin.  If this is from Lord Reinald I'd like to get more information about him since my search results on him have been scarce.  Thank you!
 

Yes, a mite or double mite from the Low Countries, late 14th - 15th century looks like a good possibility.

Let's see what we find.

Probably you have already done your research, and seen that among the possibilities for this general style (two line inscription in center of one side)  are:

Born:

(REI /NOR):  N#379852

(REI/NER):  https://en.numista.com/catalogue/pieces379278.html ;

(IOH/NEI):  N#379276

Brabant (IOh/PhS for Iohanna and Philippus):  N#312151

Namur (nAm/VRC):  N#304841

I agree that one possibility is some variant of the Born inscription.  We can possibly see REI on the top line, but the bottom line does not look like either of those others (looks to me like BhI or BLI)

Another slightly more far-fetched possibility is that it is a variant on the Brabant type where the engraver did the top line backwards, to give hOI/PhI .
