Your metal tokens from Las Vegas are likely $1 slot machine tokens. These do not seem to appreciate in value over the years for two main reasons. One, they last forever, in fact I often find $1 tokens from closed casinos in-play now at some of the casinos in Vegas. They seem to get mixed in with other tokens and continue to live.

The second reason is that most, if not all 60's tokens also exist as proofs or in other collectible states, rendering the used tokens to be valued at around $3, if that.

Of course there can always be an exception.

With regard to your Atlantic City chips, you will have to tell us what color the printing is on the Playboy chip. I have no info on the .50¢ Scandinavian Cruise chip.

I hope this helps. And if I need to be corrected, someone with better information than I will likely post a response.

Good luck,

Jim Follis
