"Anything that I collect I want in as original and complete condition as possible.
Therefor I say the covers do have a value."

I agree with you Norm. However, with reference to the question I was addressing was to the original post made by Mr. Mancuso. Do you think that his $200 strike has less a value because the number on the label of his white carboard slip cover has #44 instead of #45??

Secondly, if the old label was removed and a new label with the correct # and information was affixed, do you think that anyone would notice?
