Rich,

The chips on my web site are just my traders, I have many other PR chips in my collection. Your El San Juan $1 chip is a nice one. It appears to be a 1st issue chip, I have not seen one before. It is catalogued in Black's 1999 Catalog of Puerto Rican Chips as ESJ-1. A value has not been assigned, most likely because the chip is not traded very often. Do you another one to trade?
