As far as I can tell, there is no matching TRK order card for your PL small crown chip.

Small crown PL chips, matching your monogram, were sent to Colleen Craig, 43 Malaga Cove Plaza, Palos Verdes Estates, California, in 1981. 400 white, red, blue chips, sent in a black case. Likely bought as a gift.

Those chips have the monogram on both sides, but your white chip has a denomination on one side. They were likely made for a different customer, and the order card has been lost.
