Jim the Desert Diamond...
has just posted a similar notice, "Deadline is February 28, 2009" to redeem the old issue chips. I also found out that the old chips are still there and they are planning on renting a D-9 Caterpillar (or equal) out by WHY, AZ someplace for a cerimonial burial. I also can confirm the new denominations are $1 $2 $2.50 $5 $25 $100 & $500. They also have all new Tourney chips but I was not able to see them.
