Jon:- From your scan it also looks like the green is missing as well. It also looks like the blue is lighter.
I normally find that looking at both stamps under a U V lamp reveals if there is any other differences between the two.
Its amazing how often the sun can fade/remove different colours.
I was told by an expert that Reds fade to yellows and yellows to white and that those dyes are the fastest to fade overall. To be sure, you'd need to look under a microscope to see if there are no traces of the imprint from the yellow. Nice find though! Still interesting and fun to add oddities like this to your collection.
Thanks for the responses so far.
Brechinite: It's no surprise that the green is missing, since the yellow is missing. Where the green should be is blue, which makes sense.
philatelia: It could be that the yellow faded to white, but it's interesting how uniform the lack of yellow is on the stamp. There's no yellow anywhere. I'd expect natural fading to leave various levels of the color in place. Also, note that whatever happened to the stamp, it probably happened before it was cancelled, since the cancellation consistency is the same all over the stamp.
I'm thinking of sending it in to get authenticated, but I'm not sure what the best place to do this would be. My hope is that it wasn't printed with any yellow, but that would be very unusual.
Color missing errors are phenomenally tricky, even for the pros. There was a great article in the American Philatelic Society magazine a few months ago showing some that were oh so close but no cigar. Even one little dot of the color makes it no joy. It was a great read, I can’t find it right now to tell you which month, sorry.
But yours is a good one though! So much fun to find oddities!
I ran across a copy of Switzerland Sc. #1029 with the yellow color completely missing.
This is puzzling since I wouldn't think it would be worth somebody's time to modify.
I doubt it's just fading because there's no yellow anywhere on the stamp.
Comments?
