I was at the 4 queens last week and picked up 3 sets of matching dice from the gift shop. But they don't say anywhere on them 4 queens. just numbered and las vegas nevada. Green, red and Blue. they were packaged as a set and told they were used at the 4 queens. I have dice from the 4 queens and they say 4 queens on them. Is this something new the 4 queens is doing? thanks Brian
