That green crown up in the corner is the only one like I have seen. Of course, it is very close to the usual one that says "CROWN" on it.
I showed that chip to Dale a few years ago and he said he was going to assign it a new code. I have not seen or heard from him since. The other crown is from the Hotel del Coronado. I wish I could get more. I know quite a few people that would want one. As for Las Vegas, I'm not going to make it this year. Some things have happened in the last six months that have changed my priorities. I'm getting married again and I joined the great sea of the unemployed at the end of last year. I am planning to get to the convention next year for sure.
