Beats me, Don. Possibilities are:
The $5 Yep Lucky was their only table chip and they used Ike's for dollars.
They were one of the few casinos to follow the rules and destroyed their chips.
Someone still has them in an attic or closet.
According to Fuller, the last owner may have used "Rainbow" chips (and destroyed the others?)
Wonder what the purpose was for the $5 Non-Neg?
Borland made 3 different counterfeits, all Non-Neg
The dime and quarter fractionals are not confirmed.
There are more questions than answers regarding this club.
