I forgot to mention that the Sac & Fox posted a redemption notice for all previously issued chips and will stop accepting them as of April 1, 2008. I'm not going back anytime soon, but perhaps Mr. Lammer can trade chips in for anyone who wants to redeem their extras.
I still have plenty of the new $.50 and $1 chips, but only one $5 left for trade or sale. Please email me if you are interested.
