1911 TD.2-TD.H is currently a singleton variety (maybe become part of a family one day) struck on a brass planchet. The current census has documented 3 examples. This is 1 of 20 documented Barber half dollar transfer die varieties.
 
This example shows about half of its original silver plating remaining, a rare feature if you've had the opportunity to collect and own other Barber half dollar transfer die varieties.
