Errors from the Jesus Jimenez issue that can be found are: shifted perforations, natural paper folds and mirror impressions.
Approved by the decree #6 of January 12th, 1923. The Jesus Jimenez issue was the third stamp issue printed in Costa Rica by Litografia Nacional. And it’s key to state that quality wasn’t a component at the Litografia Nacional. Therefore, we can find some very interesting errors from the Jesus Jimenez Issue.
First, perforations. We can find some crazy stuff! Double and shifted perforations. Apparently the perforation machines used during that time by Litografia Nacional and the people operating them were the ingredients for the perfect-philatelic-storm. If you don’t believe me, just take a look at these examples:
Probably the most common errors in this issue are the mirror impressions. Basically, it consist on fresh-non-dried ink that transfers to the pane above it, creating an impression on the gum.
And last, but also my favorite of the errors from the Jesus Jimenez issue…natural paper folds.
Natural paper folds consist in the paper being folded before the stamp gets printed. After printed, the paper unfolds or gets unfolded, generating white sections on the stamp where there should be ink. For a better idea, see the images below.
If you have other errors from the Jesus Jimenez issue not mentioned here, please send me an email to firstname.lastname@example.org. I will be more than glad to share it with everyone.
