Thank you for your offer for a free keychain. I was only going to make a keychain out of the atlantis chip if it was worthless (or close to it)-I now realize that it is not. So, hence, it will not become a keychain. I will probably sell it-some have suggested e-bay (believe it or not- I have never bought or sold anything on e-bay but there's a 1st time for everything) after I find someone who can appraise it. I know it is not worth a fortune but it isn't worthless as I had thought possible because the company is no longer in business. I knew some people collected chips but I had no idea it is such a big thing. The chip is not in mint condition but I believe it to be good because other than a small nick on one side, it appears pretty good to me. In the meantime, I will keep it safe and I have promised a few people who have e-mailed me that when I make a decision, I will let them know of that decision. Thanks again and I will keep apprised if you wish via your e-mail address.
