These chips would be great examples to add to your collection if you are looking for 2 older / obsolete Las Vegas chips. The top chip appears to be N4608 and the one underneath it is N7712. Both chips are listed as "J" in the chip rack ($50-59) but these chips are far from perfect. They both display well and look pretty nice in person but the edges are rounded and have a little wear on the inlays. These chips still display well and would be a nice addition to someones collection until uncirculated examples could be found. If your interested let me know and we will try to work out a deal. Thanks a lot, Dan R-8220
