I have 60 some different matched #'ed pairs of I'm selling over the next few weeks on eBay. You may think they're a dime a dozen but at this point I do not know of any others who have collected the Colorado dice as avidly as I have since 2009 when they introduced craps to the Colorado casino floors. Those that were really collecting them 10-15 years ago have since passed, former club members like David Niver and Gary Johnson. You would be hard pressed to collect any of these pairs today simply by walking into the casino asking for them, especially matched #'ed pairs, so get ‘em while you can!! Many from closed casinos, some from open casinos but long obsolete and some current issues. Below is round #1 that I've listed. Appreciate you having a look-see!!
