1947 Una Peseta 56 In Star..maybe Valuable?

I need a good camera, but its definitely a 56. I have a cheap microscope(not good for pictures, but for my own research) that its 56 in the star. Like I said, not in particularly good condition. I wasnt even born yet and dont know much about the Peseta, other than it was mass produced like much common coinage, but was interested because of the PLUS and 56 visible in my loop and microscope, without a mintage listed.

Thank you for your reply :) Always like to learn about the coins that I have and will continue to collect as I have the means.
