THE COLOR OF THE SEAL IS THE INDICATOR AS I AM TOLD....MARKED THE NORTH AFRICAN NOTES
Who says you can't teach an old dog new tricks?
Your right on the money
Looking in Kenneth Bressett book United States Currency he says the Yellow Seal Silver Certificates were issued in North Africa during operations there in 1942. Later they were issued briefly at the beginning of the Sicilian campaign. So now we know, we even know what year the bill was issued now.
