Actually some are paulson and some are christy jones,. The $5 chips are christy jones. This can be seen by the very shinny texture inside the hat and cane. This is unlike the more textured look of the Paulsons. Also the Paulsons are a fraction smaller than the Christy Jones

The only ones Im sure are paulson are the short cane version and the $25 chips
the rest of the long cane version chips seem to be christy jones.

anyway Im no expert but from the info ive gathered this seems to be correct
