Good morning. Yep, I have done that before. I have just seen one or two down through the years which was "a number which suddenly became a ticker again". Didn't happen to me, but had other posters report that happened to them. I'm theorizing that shells are going to become more and more scarce. So I'm also thinking we could see some of them come back from being delisted. All it takes it one to make it worth it.
