Does anyone have a scan of this stamp with the gray omitted along side the normal stamp. I have 4 of these, 3 appear to have no gray. I would like to see them side by side before I spend the money to have them authenticated.
Scott 2020 standard catalogue Australia 388a is listed as gray omitted. Color detector software shows certain areas of the stamp as being gray tinted where the same area on other stamps are white. I wanted to get some input from others before sending it off for authentication.
