As stated the one on the left has been confirmed from the Burt records as being real.
The one on the right has now been confirmed as being made in 1991. The Mint closed in 1989.

Paul-Son bought the H&C CJ molds.
The one on the left is a CJ. Blanchard confirms that Paul-Son actually sold more CJ's than Cristy Jones ever sold. The CJ mold was eventually returned to PS but there is no confirmation it was ever used by PS. It may have been NG by the time it was returned.

The one on the right was/is PS's mold from the begining.
