I picked up several sticks of dice from Harold's Club and the Nevada Club in Reno this weekend. They were wrapped in the original TK Specialty foil wrappers. The wrappers were backward - foil on the inside and the date the dice were removed - or placed on the table - was written on the outside. They are all from 1995 - when Harold's Club and the Nevada Club were jointly owned and were connected with doors on the second floor.

The interesting feature is the black "H" on the backside if the center pip on the three side. You can see it on the four side shown below. Was this a common feature on dice at this time?
