Steiner sold a pile of Williams autographs over the weekend for $99. All have Green Diamond COAs. I'm seeing them all over social media with some debate about the reliability of the COA (which apparently originated from William's son). The autographs are sloppy, but if they were signed in the years/months before he passed that wouldn't be surprising. But they don't look right to me. Here is an example.
Any opinion about authenticity?
