You are asking about a 1/4 Balboa coin (KM#11) from Panama. The coin is 24.25mm in diameter, weighs 5.65 grams, and is mad of copper-nickle clad around a copper core. The obverse (front) has the national coat of arms with the words "REBVBLICA DE PANAMA" ("Republic of Panama" in Spanish) above and the date below. The reverse (back) has a portrait of an armored conquistador and the words "VN CVARTO DE BALBOA" ("One-Quarter of a Balboa" in Spanish) above. 1,500,000 such coins were produced in 1975.
Note that the "v" is a stylized use of Roman orthography, which did not have the separate letter "U" and used V as both a vowel and consonant. A number of older U.S. coins also have the same usage.
From a foreign exchange standpoint, the balboa trades at par with the U.S. dollar so your quarter-balboa coin is worth 25 US cents.
From a numismatic standpoint, acording to the Standard Catalog of World Coins, an example is worth US$0.35 in Very Fine condition, US$0.50 in Extremely Fine condition, US$3.00 in Uncirculated condition, and US$7.00 in Brilliant Uncirculated condition.
The value is for the silver only. The fact that it's proof (they all are) adds no value.
