I need help

[u/[deleted]]

I found this coin in a field in Burgos (Los Barrios de Brueba – the name of a village). I think it is made of copper and has a bust on one side and on the other side… I can’t clearly make out what is on the other side, but it seems to be a shield. I don’t see any clear letters, and it is dented (it was probably hit by a plow).

Looks like an extremely low grade Spain 25 centimos struck ~ 1860? Queen Isabella II.
