VFOG mint examples of the 4r on 1000r dull blue and 20r on 5000r grey blue from the second 1922 surcharged imperforate issue. Scott notes that forgeries of this issue do exist. However, we have not had time to research their authenticty. However, the few issues from the collection that we have taken these from do seem to be genuine. 2008 Scott cat. is $23.
