I think Ray is right - but there was also a "Red Carnation" weight made in 2002, however the Charlton Catalogue image is somewhat less than useful for reasonable identification and I don't think Frank yet has an image, or entry, for that one.
Assuming it is the 1999 version, then Frank's site shows a good image in page 11 of the "Flowers" category: "Red Carnation (Style 1) 1999 - U99190 Medium". The Charlton Catalogue states the original issue price was UK £35, US $82.50 and that the 1999 "value" was a whopping UK £250.00, US $500.00! (perhaps not many of the "unlimited" run were made??) The reality of current value may be quite a bit different from those figures!
But ... the 1999 weight does not tie up with the product number that Cazza quoted (T83469).
I'm a bit confused.
