I asked an individual from Indiana if they had any Empress roulette chips for sale and received the e-mail below:

"Thanks for asking, but I don't know the difference. I was a bartender and only play the slots. I have a lot of Empress pre opening
items and chips and coins from Vegas, including the silver collectable ones in plastic containers that you won in a slot machine. I got these years ago and some are the Seven Wonders of The world series from Aladin, I think. Let me know what exactly you collect and I will check my items."

If anyone is interested in any of the other items she has for sale, please let me know and I'll forward her your e-mail address.

Thanks!

Larry
