Chip-Master 300 Cards & Chips

I picked this gem up at a flea-market about 2 years ago. It’s a Chip-Master 300, so says the lid. It is has all the plastic chips and 2 decks of unopened playing cards. It also has levers on the side of the box such that you pull a lever and it raises that row of chips.

I knew it was old by the looks of it and then when I opened it, it smells like your grandmothers house. It was then I knew it was OLD!

The internet has not come up with any information. Google and ebay have yielded no results. The only thing I was able to research was the playing cards... Both decks are sealed. The cellophane is not in the greatest shape but never opened. The cards are marked with U.S. Int. Rev. Playing Cards Stamps. Per the internet the last time the U.S. stamped cards was the mid 1960s.

Please let me know what you think. I did not pay much for it at the flea market and am VERY curious of it’s value. If any.
