Liberia, like most countries in the world today, has figured out that coin collectors will pay astounding prices for flashy coins. They produce coins by the thousands and sell them with high margins to everyone who thinks they look nice. In fact, they look beautiful. But, when it comes time to sell such coins, prices fall like a rock.
Liberia produces hundreds of different types of these coins. This one contains 0.648 troy ounces of silver, and that is how much it is worth. At today's silver price of about $16 US dollars per troy ounce (look it up, it changes every day), the Boston Tea Party coin is worth 0.648 x 16 = $10.36.
