I wonder what the US ERRORS Book reads about these.
The US Errors Catalog does the right thing (in my opinion) and does not list color-missing errors caused by perforation shifts.
In the introduction (17th edition), they distinguish color-missing from color-omitted:
Quote:
Stamps that appear to have a color omitted as the result of shifted perforations are not considered to be color-omitted errors because it is the imprinted design that defines a stamp, not the location of the perforations, which only serve to facilitate the separation of stamps. An otherwise properly prepared stamp containing all colors does not become a color-omitted error simply because a shift in perforations eliminates part of the design. It is a color-missing error. Color-missing errors due to perforation shifts and other production anomalies are listed in the Scott Specialized Catalog of United States Stamps and Covers.
I still quibble that they call it a color-missing
error and not a color-missing
freak or oddity. If the perforations are shifted half an inch in one direction it is called a misperf freak, but if they are shifted half an inch in the other direction it becomes an "error" with an inflated price tag. I don't get it.
