Could be a Spanish Savings stamp. The translation of the words is Caja Postal de Ahorros (Postal Savings Bank).
possibly your stamp is this one.

Scott does not, as far as I'm aware list these.
The above being said, posting an image of your stamp in question would go much farther towards identification.
It's a Spanish stamp with a crown on it and it seems to be rather old and if I'm reading the postmark correctly it's from 1917 and on it it says Caja Postal de Ahorros. It has a yellow background and green printing and it's for 5 centavos. Any idea? I couldn't find it in Scott. Thank you.
