Over the past two years I have been having an on-going conversation (some would say - debate) with one of my most supportive Standard Catalog (coins and paper money) contributors.
We have been discussing the fluorescence characteristics of bank note ink and paper; and if that would be a good thing to add into the descriptions of the bank note listings in the Standard Catalog of World Paper Money.
Well, I have decided to proceed with this process, and in the forthcoming 15th edtion of the Standard Catalog of World Paper Money I will start to add UV characteristics.
So, let this be a heads up to my contributors. Get out your UV lights! I probably will not create new varieties from US charastic changes, but will add information to the existing varieties.
The catalog is still a reference of what one sees in normal light conditions.
