This coin commemorates José Julián Martí Pérez (1853 to 1895) who, according to Wikipedia, was a Cuban national hero and an important figure in Latin American literature. Through his writings and political activity, he became a symbol for Cuba's bid for independence against Spain in the 19th century, and is referred to as the 'Apostle of Cuban Independence.'
The coin contains 0.773 troy ounces of silver, and that give it value. The base value (BV) is found by multiplying the current price of silver by 0.773. If, for instance, silver is trading at $14 US dollars per troy ounce, then BV = 0.773 x 14 = $10.
But the coin also has value as a collectible item. The total value, then, is about:
worn: BV + $5
average circulated: BV + $10
well preserved: BV + $25
fully uncirculated: BV + $60
