| If companies issued more than one denomination
of bond, they typically used different colors for different
denominations. I have discovered no clear-cut relationship
between colors and denominations.
For instance, 35% of all $1000 bonds included some shade of green.
However, the relationship is statistically insignificant because
29% of all bond denominations are green.
Concerned about the variability in coloration? Read How
variable are certificate colors? Also, if you want to report
new colors, you might also read Reporting
new certificate colors.
When I report "colors", I generally mean the colors of borders. If there are no borders, then "color" refers to text color. Color descriptions of very scarce certificates often depend upon very old descriptions by dealers and catalogers. IF those people reported underprint colors instead of border colors, or made mistakes, then those old mistakes may persist.
Underprint colors RARELY change without similar changes in border colors. For space reasons, I do NOT report underprint colors unless someone has contributed evidence or otherwise suggested that underprint coloration is known to be variable. |
