I have a couple of chips that I picked up in a large lot. THey are similar to the PY-EP and PY-ER (Gilbey's Port and Gilbey's Rum).

These are the same chips (made of wood) but are "Gilbey's Spey Royal" and "Gilbey's Dry Gin".

Are they the same value?

Should they be cataloged as PY-ES and PY-EG?

Any help is appreciated.
