Poor condition medieval coin to identify [解決]

I know the condition is very poor but i hope someone might help identifying this coin.

25-26mm diameter

I can distinguish "ET.RD" or maybe its "FERD" piece of text
On the back also "RFO" or "REO" piece of text

My best guess - Ferdinand of Bavaria coin -, a Brabant Liege Liard or smth

On the back may be REC lettering.
And yes, other side may have FERDI as start of FERDINAND lettering.
Perhaps:
Spanish Netherlands
1 Oord - Ferdinand

Edit. Lettering may be >
FERDIN ET ELISABETH // FERD COM DE LIN RECHEM

Or perhaps >
Belgium. Reckheim. Ferdinand d'Aspremont Lynden (1636-1665). Duit
from which gives REC and FERDI lettering.

It's the shield of Liege

引用する: "Frenchlover"​It's the shield of Liege

​That's what I thought but all center shield of Liege seem to have a line whereas this coin has some kind of spread wing eagle or bird.

At least all the ones I own or browsed.

Why not Ferdinand D'Aspremont-Lynden (*1611 - †1665), that might lead to a contemporary counterfeit from Reckheim
duiten.nl, De catalogus, Graafschap Reckheim

even though it is not the same coin. It has similar lettering, plus
the eagle with wings in the centre of the shield design.

Thx guys, i think you nailed it !

Once again ZacUK, Reckheim split in several places as Dutch republic, Spanish Netherlands and even Liege is a pity for our catalogue that should gather these coins of this HRE county

frenchlover, I found this one mis-placed in Liege and will submit the modification request: https://en.numista.com/catalogue/pieces187126.html

Are there others in Liege?

I've been working on some areas of the catalog in Low Countries, but not yet Reckheim.
