The " L mold " chips and the " Sq Sq Rect mold " chips that you show are from the 55 Club in San Jose , CA .
I bought some of both kinds from a relative of the owner back around 1990 . It was originally called " Oswald's 55 Club " ,
then shortened to just the " 55 Club " . The Sq Sq Rect mold denoms that I bought were the red 25 cent
and the yellow $5.00 chips ... The L mold denoms that I bought were the green $1.00 , yellow $5.00
and the $20.00 Maroon /2 white . I am positive that both types of chips were used at the " 55 Club "
in San Jose , CA .
