For emergency workers we make this special interlocking quarter with a firefighter shield and a police badge on either side. They are cut from the same coin and interlock perfectly together.
It has been hand cut totally by hand into a quarter by our small 6 member team at NameCoins. It includes 2x 20" smooth, strong stainless steel chain (one thin and one thick).
If you are interested in making this more customized for you, finding a new design, or simply wanting to see different chain options look us up:
