My best guess is that your coin is a one-half ("medio") balboa piece from Panama. Panamanian balboas track the U.S. dollar on a one-for-one basis and are struck on the same planchets. Your 1966 coin was thus struck on the same 40% silver blank used for Kennedy halves of the time, so it would be worth $3 or $4 for its metal content.
Panamanian currency is linked to the U.S. dollar at a "par" ($1 = 1 balboa) exchange rate. Your coin is the Panamanian equivalent of a U.S. dime and is worth the same amount.
What ever you can get someone to pay you for it, just like anything else.............

Currently circulating coin -- no collector value.
A 1975 medio Balboa (half Balboa) coin is made of copper-nickel and corresponds to a US half dollar in size and composition. As such, it has no real added value if it's in circulated condition. For an uncirculated or proof half Balboa, prices range from $5 to $10 each. The exact price one will get will depend upon the condition of the coin.
A 1966 Panamanian coin that says "Un Cuarto de Balboa" (which means one quarter of a Balboa) and "Repรบblica de Panamรก" typically has a collector value rather than a significant face value. These coins are made of copper-nickel and are commonly found in circulating condition, so their worth would depend on factors like condition, rarity, and demand among collectors.
