Lot 360 Mauritius Used in Argentina SC#79 16c on 17c Rose 1883 Surcharged Queen Victoria Crown CA Keyplates, With SON B32 Buenos Aires Barred Numeral Cancel, Scarce, Unusual & Unlisted, A VF Used Single, Estimated Value $50

A VF used example of the 16c on 17c rose from the 1883 Surcharged Queen Victoria Crown CA Keyplates, with SON B32 Buenos Aires barred numeral cancel, scarce, unusual & unlisted. This one is a real mystery, as there are no catalogue listings for Mauritius used in Argentina. But B32 definitely is the hammer for Buenos Aires in Argentina. So my guess is that this franked a ship letter that passed through Argentina and was cancelled as it passed through. 2022 Scott Classic Cat $2.4. Our estimate of the value based on the condition is $50.
