Hello and welcome!
There is a glossary in the Resource section to help with our "chipping patois".
Paulson/GPI makes/has made all sorts of chips that you will see many examples of, based on the different molds used in the compression process. A few of the rough categories could be as follows:
"Hat and Cane" - unofficially divided into THC (which has a ring outside of the hats and canes and a smaller recess area) and RHC (which has a larger recess area)
"Roulette" - with the word ROULETTE stamped near the rim
"House Mold" - made for casino customers with their specific property name stamped near the rim; many examples of these in Las Vegas
"Paulson House Mold" - used for some of their promotional/advertising chip series, has the words "PAULSON CHIPS" stamped near the rim, e.g. CDI2005
"Suits Mold" - sets of the four suits symbols separated by a single top hat/cane, used for many fantasy series, e.g. Avalon
"Pineapple Mold" - used for Le Paulson Noir fantasy series
"Diamond Mold" - an old mold of a series of diamonds within an outer ring (similar to the THC)
I'm sure there's more.
Feel, sound, playability, and durability characteristics can change with the type of mold used, the size of the chip, if there is lead content or not, if there is an inlay (and how big it is) or if there is a hot stamp, etc. Keep your eyes and ears open, look at the stuff that's offered for sale by members and vendors alike (because there's a huge variety out there). Try and get samples before you buy. Or, in the future when physical distancing restrictions ease up, try to contact other chippers in/near your area to see and handle some representative chip sets. You'll find friendly folks all around!
