Nice coin, jmjkks. That's a big old condor, a bird you see on most Chilean coins. The peso contains 0.7234 troy ounces of silver, so that makes it valuable from the get-go. Look up the current value of silver at kitco.com, multiply it by 0.7234, and that is the basic value of jmjkks's coin. The 20 and 50 centavos pieces carry the same design and the silver content is proportionately less. There are 100 centavos in one peso.
There are similar designs for Chilean coins, but this page applies to coins with the condor and feathered shield designs shown in our photo.
