Is there an easy way to tell is a chip is still live? I know that the Chipguide supposedly tells you what is current but I think a lot of the information may be out of date (there are chips submitted by Greg Susong still listed as current). With all of the duplicate chips that I got in the collection I am thinking of returning some to the casinos but need to figure out if a trip is worth it to certain locations. Thus I am wondering how to tell if a certain chip is current. Is there an easy way?
