I have this coin, and have no clue how to figure out how much it's worth. Can somebody please help me?
On the front of it, it says francisco franco caudillo de espana por la g.de dios. 1957. Then on the back is a picture of an eagle with some kind of shield. Also on the back is a star, and 5 PTAS.
That 5 pesetas coin was made for circulation between 1957 and 1972. The "1957" that you mentioned is the authorization date while the production year (two digits) can be found in that star you mentioned. Mintages are between 13 million and 108 million, so don't expect much in terms of value ... Christian
