Tairyoku is a form of karate and the "TSKC Cachers" are British geocachers Jolly Green Giants and Sensei TSKC. Together they issued this personal geocoin in April 2007, but in very limited numbers. There were only 50 antique silver geocoins, and 10 polished nickel. A couple months later, they issued 150 more coins in gold, and 50 in black nickel, in order to get a custom icon.
