Jorgeke,
You're in the right area; keep swinging.
1846 "Estado Libre de Chihuahua" 1/4 R copper. 26mm.
This coin was illegally struck in Pennsylvania, but (obviously) circulated in Mexico.
Don in SoCal.
Two additional and similar 1/4R coins with the same design exist in higher values.
ESTADO DE CHIHUAHUA (1854-6) and DEPARTMENTO DE CHIHUAHUA (1855).
Keep swinging,
Don in SoCal
Thanks for the post, Jorgeke. I always enjoy seeing your pictures of such a different area and people than we have here in the North. The coin is very nice and having Don provide the details on it, as he usually does, really adds to its interest for me. Otherwise, I would have little idea what it is.
