Hi Kris --
Coinage is scarce in Cuba. In 1952 they issued the pictured 40 centavos coin. In 1953 they issued a 50 centavos coin that shows a scroll on the reverse.
Assuming you have the 1952 40 centavos piece, then it ain't half bad - these coins were a one-year type, and less than one of these were minted for every 700 Lincoln pennies made by the US in the same year, to put things into perspective. This gives these coins decent collectible value, especially in higher grades.
Here are some approximate catalog values for the Cuban 40 centavos from 1952:
worn: $8 US dollars approximate catalog value
average circulated: $10
well preserved: $12
fully uncirculated: $25
Coins that are fully uncirculated and with a strong eye appeal can sell for upwards of $50 or more.
Be sure to check out the 'Important Terminology' page on the top left to properly interpret these catalog values.
A damaged coin will be worth its silver value. Look it up at a site like kitco.com - it changes every day. with 0.2893 troy ounces of silver per coin and silver prices of $24 US dollars per troy ounce, each coin is currently worth in the neighborhood of $7 from its silver content alone.
