Purple Shaftieuland
It is based in LaPorte, Indiana, USA. A set of coins from 1970, conceived by Mr. Bob Kolosa (Box 411, Westville, IN, 46391). There is the Full Shaft, the Half Shaft, the 1/4 Shaft, 1 Twist, and 1 Nudge. These five coins as a set is available in Brass and Unanodized Aluminum. These coins were his humorous way of expressing contempt towards all the non-circulating legal tender (NCLTs) and commemorative coins that were (and still are) being minted specifically for collectors. He basically thought that the only purpose of these coins was/is to separate us from our cash, and were simply a money-making scheme. In the broken English of Chief Weeskee Rooyoo Kissieutieu, these coins are “also call ‘transportation tokens’ because you buy and get taken for ride.” I reckon Mr. Kolosa (and the Chief!) would feel equally as angry about coinage from nonexistent/ephemeral/unrecognized “governments” (I didn't chance to ask him!). Ironically, Mr. Kolosa's coins have become sought-after collectors' items. As unique as they are, they really fit quite nicely into this family of unusual coins. Images of the coins can be seen at: http://69.55.175.34/dan46.html. On smaller coins "In Forinade We Trust 1970" is written while on  larger 38mm diameter coins, the name of 'Chief Weeksee Rooyoo Kissieutieu' is also written as shown below.

Below are the images of 2 very interesting info sheets, one has the specifications of the coins and the National Anthem and the other, the humorous reasoning behind the coins !
I purchased my  both Unanodized Aluminum and Brass sets of coins from Mr. Oded Paz (go_4_it@sbcglobal.net).
