I now have some of the cocktail ladies saving their roulette tokes, and I buy them from these ladies instead of them turning them in.

The scan shows some I got last week for one of the cocktail ladies.

My question is, I know that roulette chips have letters or numbers to tell which table they belong to.

Here you see a MGM chip with the letter Y
I know that the MGM does not have 25 roulette tables. Could this chip be a back up chip?

Thanks for any help, and I'll be sending these chips and some others out to Neal Silverman in the next few days for his roulette raffel.
