Here is a Doc Rebuild story where he accuses others including me of changing a Bloomington Gold Certificate from silver to gold. This was a 68 L89 Vette I owned and then Tim Gilmore owned. It in real life had a real Gold Certificate and was shown in the Bloomington coverage issue of Vette Vues show the list of gold winners including this car. How it scored silver on the judging sheets but awarded gold I have no idea but I'm sure nobody faked anything. I even called Doc and spoke to him but he never mentions that.
