I've a couple of stupid questions that I'd love to have the answers to.

1) I have a chip like the one pictured that I didn't see used at the casino when I went there last week. Can I still use my chip to play there? I have several chips like this.

2) What book(s) do I need to buy to know what the hell I'm doing? I need help especially with valuation. I've seen several, but they're a bit pricey and I'd rather just buy what I needed.

3) Has anyone tried ultrasonic cleaning for their chips? You know, the kind they use for jewelry. Any other cleaning tips?

Thanks for any and all help! You guys are great.

I have a number, but I can't find the card at the moment. :)
