20 Dollar Coin Certificate?

I think the plane ticket to Africa will set you back a bit more than 20 bones
NCM is nothing but a peddler of overpriced junk

It's worth nothing more than silver melt value.......whatever it "weighs" is what it's worth.......and that's it !
Liberia, Africa does have an association with the U.S. (from the Carter days I believe) and has minted things before with Kennedy...even Reagan I think.
So, in things like that, with foreign countries minting/printing U.S. Commemorative things and tied in with "private coin companies".......melt value only....
If it didn't come from the U.S. Mint.....be VERY skeptical !........worse yet "The Liberian Government" (or any foreign Govts. printing U.S. associated things like our Presidents, 911, etc. etc.)
99.999 Silver can be a "eye catching" sales technique.....but it isn't worth anything beyond the silver content in this case for sure !

The 99.999 silver part sounds good, but the word LEAF is bad when it comes to silver content, meaning there isn't very much of it. A very,very thin layer on each side of this bill and presto, you have silver leaf.

Liberia has a stronger association than that. It was founded by the American Colonization Society back in the early 1800's as a place where freed American slaves could be "sent back where they came from". Indeed, much of the modern civil strive and warfare in Liberia in recent years has been between descendants of the freed slave "settlers" and descendants of the native Liberians.

As a de-facto American colony (even though it declared independence in 1847), it has had very close ties with the mother country, including the currency. However, you should be aware that the US and Liberian dollars no longer circulate at par as they once did; there are currently 63 Liberian dollars to the US dollar, so the "face value" of L$20 is now about US30¢.

Finally, note use use of the phrase "private striking". I seriously doubt that the present government of Liberia is aware that the NCM is still making "coins" like this in their name.

I've seen a few commercials for this lately, much like the 911 commemorative coin that another user mentioned, and I can't help but feel kind of sad. I'm not sure which is worse - that private companies like these exist at all, or that they are willing to use a national tragedy to try and make a quick buck.

My own feelings aside, as others have mentioned, pressings like these are worth only the melting weight of the silver. The funny thing about the way they are advertised is that they say they are made with ".999 pure silver-leaf!" - which is a great way to fool people that don't know the difference between "pure silver" and "pure silver leaf" - most people, I would venture.

"Metal leaf" is an extremely thin layer of metal - foil thin, really - that is used purely for decoration. Gold leaf, for example, is generally pounded down to about 1/10000 mm (yes, one ten-thousandth of one milimeter, or 100 nanometers) in thickness. 2g of solid gold can be pounded into a one square meter (1 m^2) sheet that is 100 nm thick. Assuming (just for illustration) that silver leaf is the same thickness, that ".999 pure silver-leaf" you get on that metal bill is .0001mm thick around the outside of the bill. The rest of the "bill" is who knows what - not silver, at any rate.

For kicks, let's run a few numbers. The present bid value of an ounce of silver is $18.84 USD. So a gram of silver (1oz = 28g) is $0.67 USD. Now, assuming that silver leaf can be pounded into sheets of similar size/thickness as gold, let's take a look. The dimensions of this "bill" are 3.125" x 7.375" = 23.1 square inches per side, so a total surface area of 46.2 square inches, or 3.84 square feet.

If the surface area of these bills is roughly 3.84 square feet, then assuming the thickness noted above, we can set up the following ratio: (2g/3.2ft^2 = x / 3.84 ft^2), and find that the amount of pure silver needed to produce enough silver leaf to cover this bill is 2.4 grams. At a value of $0.67 / gram, assuming pure silver is used (.999, close enough), you're looking at approximately $1.34 of silver leaf in each of these bills - assuming you don't lose *anything* in the melting process.

Now, admittedly, I made a few large assumptions concerning the thickness of the leaf used, the amount of pure silver required to produce that much silver leaf, and so on - but you can get a general idea of just how much "silver" you're getting with one of these.

Not much.

Silver and Gold Leaf is what I use when I work on firetrucks and signs, I definitely know how thin that stuff is!

It's $20 legal tender... 20 Liberian dollars.
What is the exchange rate on that nowadays?
Maybe 12 cents?

Well, the dollar IS devaluing more and more everyday...
