This is up for auction by the Victorian Casino. I cant find it in any of my books. They call it a trade stimulator but it looks more like a slot. White City was part of the Columbian Exposition held in Chicago in 1893. What catches eye is the 50 coin entry amount. Fifty cents was a lot of money back in 1893.
The spelling of the word "favourites" also makes me wonder if this may be a home made conversion.
