Hi Carl,
I'm only asking because from what I can tell, only 2 types of Vineyard repros were made, one set was made by Blue Chip company which has the shell mold (aka flame mold) and the ceramic repros made by Chipco, which includes both denom and non-denom chips.

If your chip has a hat and cane mold, I would think its a legit Paulson chip and you wouldn't need a black light to verify this.
Regards,
Greg
