Unknown coin, perhaps a jetton/token [решено]

Hello. I need some help to identify the following item, included in a copper lot (mainly french and spanish netherlands coins, 15th-19th c). Ø 25 (I haven't weight it), and it's made of copper.
In one side, I think there is a coat of arms with 4 pales/bars (like Aragon), and possibly leaves above shield (like guernsey coins). In the other side, another coat of arms with the crude image of a castle with 3 towers inside (that's I think), and a letter “A” (or a triangle) on the left. No more letters can be appreciated (so at first I think it isn't a coin, most likely to be a token).
Thank you very much in advance

Castilla ?

Yes, I have thought in the Castilla coat of arms. But I haven't still found a coin/token with both images (Aragon and Castilla). And it seems to be not very old (neither very recent). A nice mystery for me

Señal, a local issue of Castelló de Ferfanya, in Pincipality of Catalonia, 1479-1516, Cal#208, Cru#1390.

Look for some examples in www.acsearch.com, searching: castello cru 1390

These local coins are difficult to find...
Good work!!

Incredible!!! Thanks a lot, muchísimas gracias. I had not been at all able to find the solution
