Until today I wasn't what you would call an error collector, well I may have to re-think my position on that status. Have had these two notes (and some others) around for years and never gave them a lot of thought. Was reading error note section in Friedberg and error note comments by Fred Bart so: just for "fun" I decided to send them for grading.
Very nice errors. It seems to me that errors on coins seem to occur more frequently than on paper money. Than again, maybe the paper money errors stand out more.
At second look I can see what appears to be a light staining and wrinkled so I would agree. But a very nice error.
