Here is a great site you can take your time in looking through. http://www.casino-tokens.com/ Dan has everything you are asking about to get a very rough idea as to the value. With these types of tokens it can be easy for selling as getting the right buyer. I have found sometimes the larger the grouping like this the better the deal can be made since you are taking a big grouping off the sellers hands. I would check the $1.00 1965 set though. They were made in .999 silver and also in clad. Naturally the prices are a big difference.

As for the plastic trinkets if they are from Nevada casinos certainly they would sell here better than non Nevada. Prices for selling and getting a buyer most around a buck each. Harder to find a bit more and commons maybe a couple each for a buck. I have a couple hundred from Nevada but have rarely paid more than a quarter each. A lot I get if I am buying a silver strike at a show and say how about I buy this and you throw in this trinket. I do enjoy them and if you end up with some I do not have I would not mind trading or maybe buying at the right price.

Hope all this helps,
