Identifying stamps from the St. Kitts-Nevis King Edward VII issues watermarked Crown CA involves sorting between the two watermark options: Crown CA and Multiple Crown CA (MCA); determining the difference between chalk and ordinary paper; and sorting some color varieties. The stamps printed on paper watermarked Crown CA were initially issued beginning in 1905 until they were replaced by a new design beginning in 1920.

If you have trouble determining the watermarks, try looking at them face down against black paper. The stamps watermarked Crown CA will always be centered fairly well on the stamp, and the design does not repeat, so even if you can not see the entire watermark, the CA will always be toward the bottom, instead of letters to the sides for the watermark Multiple Crown CA. See the images of the two watermarks below for reference. They are shown as normally seen from the back.

Once you have determined the watermark, the next step for three of the stamp values is to sort them between chalk and ordinary paper. The initial stamps were printed on ordinary paper. The later issues were printed on chalk coated paper. Although a silver coin will draw a line when rubbed gently against most chalk paper, I find this does not work very well for the KEVII watermarked MCA issues. I look for a shiny coating on the paper when viewed under a good light source. You can also rub your finger across the face of the stamp. It will slide easily over the chalk coated paper, and will feel like it is catching against the ordinary paper. Another test is the quality of the impression. The chalk treatment was used to insure a better quality printing. For the record, the term chalk is not scientifically accurate, but it is the term that has been used in the catalogs. All of the stamps listed below are identified as either Ordinary or Chalk paper so you can easily find some to identify and compare.

Once you have determined the watermark, the next step is to sort by the colors. Color shades can be difficult to sort, especially when you only have a couple of stamps to compare. They typically occur when the stamps are printed after the initial printing. Today we have computer color matching, but during this time it was done by hand with components that might differ from the original ink formula. I like to place the stamps against black and then white paper and view them under a strong light. The images shown attempt to show the colors, but they do not show them as well as viewing the stamps in person. So use the images as relative indicators.

Unlike modern stamps which are issued in the millions, definitive sets from this time period were issued very conservatively. I do not have the printing details, but it would be safe to assume the 5/ issue was printed in a quantity of less than 5,000 based on other issues of this time period.

The catalog numbers are from the 1980 Commonwealth Five Reigns Catalogue (CW), 2013 Stanley Gibbons Stamp Catalogue (SG) and the 2011 Scott catalog (ST).
