I've never seen Fun Nites on that mold either (not to say they don't exist). As far as I know, the PAULSON CHIPS mold has been used for five different chip lines and samples:
- Pharaoh's Club & Casino
- Paulson Classics
- Casino de Isthmus City
- National Poker Series
- The Authentic (shaped inlays)
- Fun Nite (hot-stamps)
- GPI/Paulson manufacturing samples
The first four were all introduced circa 2004-2005 or so, after the reverse-merger that created GPI. The Authentic line came later (2007-2008).
Also noteworthy to mention that there is more than one version of the PAULSON CHIPS mold. The diameters of the center recess area differ.
