Pre GPI, PS used to make the notched samples and give them to salesmen until gaming raised cane!!!
Actually a $500 notched sample got cashed in a Mississipi casino. That was the last straw.
Good story on that one for another day.

At one time I was "given a gift" of a 500 chip case full of both notched and un-notched high denom samples up to $5,000 from all over LV. The un-notched were all $5 and $25's. There was some with different inserts than the actual chips.
There were a number of your chips in it, both notched and un-notched, and with and without the PS logo on back.

Salesman said this when asked about your chip.

Becky Behan ordered a new rack with that inlay. She never paid for them. They were never delivered. If I remember right the order was never made. Just the samples both notched and un-notched were made.
