I bought some old generic Vegas slides a while back only knowing they were of gambling scenes. Pleased to find out that not only are they of the Mint (guessing late 50's/early 60s), but I was able to color corrected them somewhat.

There was a topic not too long ago about "Where are the early roulettes from the casinos?". This answers the question for the Mint at least.

Those should be silver dollars on the roulette table, but they look like tokens to me. Not an expert.
