The three chips below are all different. Were they intended to be this way or do we have a very strange fluke?
The edge markings on all three are identical "limited 2000" and " June 16th, 1999"
The first one obverse and reverse both say Fiesta & Chipco/Archie Black Founder
The second one has Fiesta & Chipco/Archie Black Founder on one side and Celebrating 11 years of Chipping/Archie Black 11 years of service on the other.
The third one says Celebrating 11 years of Chipping/Archie Black 11 years of service on both sides.
