You should have seen what Enron certs were going for on Ebay at one time. Low denomination certs are still worth more than the actual shares ever were. A two share cert used to go for hundreds and hundreds of dollars. Here's one still going now, although I don't think they are the hot item they used to be.
Somehow I don't expect CKYS is going to be in any demand though....hehe. If any actual certs ever existed that weren't printed on a dot matrix printer ;-)
