Gamblers General Store used to have packaged sticks of many closed casino dice for sale in their store. They also had huge bins of defective or cancelled casino dice you could pick through. This was 15-20 years ago and I haven't been in recently. I remember asking if they had any Sahara dice and the lady said they were out but would have some more in a few weeks.

One of the reasons I could never get very interested in collecting logoed casino dice. I assumed they had the stamping dies and were reproducing the old ones.
