I can give you a partial estimate on your casino chips anyway. Typically if you have fairly current casino chips and they are in excellent condition, you may be able to get from $1.50 to $3 per chip on eBay for them. Recent $5 chips go from $6 to $8. To get anything higher for a chip would usually mean it would be a rarer, out of circulation chip and must be in very good to excellent condition.
If you bundle all of your 45 casino chips together and put them all up for sale on eBay in one auction, you may be able to get between $65-120 for them. It may be wise to scan eBay for what the going prices for chips are.
I'd invite you to post on the ChipBoard message board as well. This is where many CCGTCC members hang out. If you post a scan you could probably get some quick offers for all your chips.
