Hi again! Sorry,you have also some very low collectable values Panama coins of copper-nickel. The KM Catalogue given values are:
5 centesimos 1982 = 0.25 usd.
Medio balboa 1973,1980,1982 = 0.75 usd.
Modern coins (post 1948) made of non-precious metal are worth face value, or a little more if in top-notch condition. See the page below for a discussion of what can make modern coins worth more than face value:
Thanks for the info
