While this is considered to be an EFO, your examples are not the conventional color shift error. The effect in the right stamp (blue in the red areas, and/or vice-versa) is known as ink bleed and is rather common for stamps printed by the Giori Press (up to 3 ink colors with a single plate).
The stamp on the left, technically is a shift, but caused by a misalignment of the roller applying the ink. In this case, the misalignment is horizontal. You will notice the wrong color appears largely on the right of side of the affected design elements.
In your examples, they would be conversation pieces, but the ink bleed (or roller shift) is not significant enough to warrant any premium. In fact, they would more likely be considered to be flawed.
However, stamps with a greater ink bleed or roller shift (affecting a significant portion of a design element, or even resulting in a color mix) might attract a small premium.
The pics are nice and clear.
Very cool, thanks for the info khj!
Hi Every one! I finally get to ask my first question.....s...! lol
I've finally gotten some form of organization going and have been taking the time to compare some of my stamps against each other. I came across these C90's and noticed some color issues going on and so was wondering if this would be considered a color shift error (albeit a small one lol) or something else? and do things like this increase or diminish a stamps value? (considering these aren't particularly rare or interesting one's im sure it doesn't matter much, but was just being curious).
Mucho Gracias!
Robert
PS. some follow up questions lol-- is this the correct place to post this query?, is the Photo i scanned clear enough?, and....ummm... how is everyone's day coming along?
