What I mean is (I bought them to see, always fun learning) from the printing and size, I'd guess they were dispensed as a prize or purchased in an arcade machine/carnival situation. There's are a number of reasons. The litho printing is that kind of brown purple that the arcade cards were printed in. I don't know why they didn't use black? Maybe cheaper ink.

Until someone has a better description, please do, I'd say encased Litho arcade tokens.

The size and the style of printing, big dot screen, colors, Etc.

The flag and the good luck are also on those machines that let you stamp letters. At best 40s, maybe early 50s. Made the movie Gilda in 1946 and I see many photos from that in a black strapless evening gown, hair style the same, looks very similar. Aluminum was also big then. I'm sure some of you token folks can ID the era and many more like this. But not a poker chip. And after 1946...

By the way: Her real name was Margarita Carmen Cansino Not a Rita in there.
