Challenge coins have been popular with the military for a long time. Now Fire Departments, Police and EMS are also using these finely detailed pieces to add to their tradition. The most common size is 1.5 inch, we produce up to 2 inch coins for common use and also limited edition commemoratives. Coins can be individually serial numbered, sculpted in 3D, and are available in many finished including gold, silver, antique gold, antique silver, and two tone. Each coin comes with a special plastic case to proudly display these incredibly detailed originals.
