This is not a US Mint coin. It was made in Liberia, the composition is copper-nickel and is not a US legal tender coin. It has no numismatic collectible value. It's worth only what you can get for it.
I have a republic of Liberia coin as well, and the certificate that came with it states it is copper-nickel.
No silver. They are copper-nickel
If it's silver, then at least $30.00
The only silver-colored coins minted by Liberia in 1996 were composed of Copper-Nickel (there were also two gold coins produced in that denomination in that year).
In 1993 the Republic of Liberia issued a Nolan Ryan 10 dollar silver proof coin. The value of this coin is about $15.
See website: American War Library
The book value is about 8 to 10 dollars in the Krause Standard Catalog of World Coins. The ten dollar version of the same coin has one once of silver so has the real value.
It is 1 troy oz of 999 fine silver. So its value is the current silver price for 1 troy oz. Depending on its condition there could be some additional numismatic value to collectors too. Current silver price as of this moment is $34.28 per troy oz of fine silver.
Silver Air - Czech Republic - was created in 1995.
If it is a $10 one ounce fine silver then at present it will sell for £16 (thats just for the silver content) because it is a Star Trek Collectable expect that price to double. They should be selling on Ebay for around £30 (sterling)
Liberia has produced at least 100 different Twenty Dollar coins since 1983 (mostly from about 1997 onward). The silver content varies by the issue, but the most seem to be either about 2/3 of a troy ounce or about 1 troy ounce.
