There is a ton of information on the web about the thousands of GAI authenticated forgeries with Mike Baker's name on the COA. But check out the below Ebay seller. Look at his photographs of the GAI cert. He conveniently cuts the GAI cert just above where Mike Baker's name would read. Of course, these Mike Baker certed forgeries are very obvious without the GAI cert.
