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.
Panama's currency is linked to the US dollar 1-to-1, so a Panamanian centisimo coin is the same as a US 1¢ coin. The two coins are even the same size and composition.
Currently circulating coin -- no collector value.
The value of a 1982 Medio Balboa coin can vary depending on its condition, rarity, and collector demand. As of September 2021, a circulated 1982 Medio Balboa coin is typically worth around $1 to $2 USD. However, if the coin is in uncirculated condition or has certain desirable characteristics, it could be worth more to collectors. It is recommended to consult with a numismatic expert or refer to reputable coin pricing guides for a more accurate valuation.

Panama started minting this Type of coin in the mid 1930s'. The last year of mintage was 1947. The Medio Balboa is their 50 cent piece. On the Front Obverse) of the coin is a Knight with rounded helmet. with MEDIO BALBOA at the top. On the back (Reverse) is an eagle perched above a Coat of Arms. Also on the Reverse in very small print is the word ley, which means purity. And .900 which means 90% Silver. Also on the Reverse is Gr. which in Panama means Grams(in America this stands for grains). Next to the Gr. is 12.50. This means the coin weighs 12.5 grams. 450,000 were minted. So it is not a Rare coin. With Silver at $12.90 per oz (Aug. 20011) if the coin has regular wear is worth between $14.00-$20.00. If in Mint condition it could be worth around $100.00.
