This set is so unusual I really don't know if I have the ability to describe it fully. This is actually a THREE coin issue that was a joint project of Liberia and the Democratic Republic of Congo in 2004. The coins are:(1) a Ten Dollar silver coin from Liberia, which is actually a working sundial. It has a diameter of 38.61 millimeters and was struck from 25 grams of .925 silver. (2) a Ten Francs silver coin from the DR Congo of the same composition and dimensions as the Liberian coin, which is actually a working compass. (3) a Five Francs iron coin in the shape of a teaspoon, which when placed on the compass coin acts as a needle and points North. The three piece set comes in a wood presentation case with three Certificates of Authenticity, one for each legal tender coin. I have loaded six images, so although it may take some of you dial-uppers some time to load all the images, I think you will find it worth the wait.
