I finished going through a hugh box of Forever Liberty Bell stamps all mixed dating. I found that one that looked unusual in color. Can anyone let me know if this is a error stamp that may be worth some bucks. I looked over the stamp for postal marking scrapings, but this is definitely in the print of the stamp. I also have about fifteen of these with the offset color of orange around the Bell holder which is normally Brown. This orange is like an outline around the one or two sides of the Bell holder and bell.
