Here are three interesting coins that you might like. #1: This interesting pattern piece was one of the proposed designs developed in 1999 for a new $1 coin. The design is possibly modeled on the $20 Saint-Gaudens coins made from 1907 until 1932. #2: This interesting and unusual coin from Palau, an island nation in the Pacific Ocean, certainly proves that it's too hip to be circular and instead opts for a star! Now that's what I call interesting! #3: This coin definitely is the most unusual I've ever seen. It's 3-dimensional! The coin's shape is an octagon, but it has a large pole sticking in the middle! Made to celebrate astronomy, this certainly is my favorite out of the group.
I consider items #2 & #3 novelties. I wouldn't call them "coins" regardless of their designation as such.
Does #3 have a numeric value struck on it? My eyes aren't good enough to detect it, if it is present.
I do like number three. I have a similar piece (but it is missing the little bar that stands up on it) that is a sundial!
I've got 3 more coins to show you. 4: This coin is a 1974-D $1 Ike with 3 clipped planchets. This coin is truly unusual in a sense, and is certified by PCGS. 5: This may look at first like a 1906 Indian cent, but by closer examination it is an Indian head cent struck on a $2.50 gold coin planchet. 6: This piece was part of a extremely rare 1866 aluminum date set featuring every coin minted for circulation at the time, from the cent up to the double eagle.
Sorry, I thought you owned these coins and could comment. If it doesn't have a numeric value struck on it, then as stated previously, it is not considered a coin. It might be exonumia, but only if it has some bearing on numismatics, not astronomy.
It's a bullion piece. http://www.apmex.com/product/69736/liberia-2004-silver-10-sundial-time-is-money
Cook Islands and Isle of Man are especially infamous for issuing commems every year. In fact, they make up about 90% of the catalogue listings for IoM.
