Hereunder a scan of 3 stamps ( the value and type of the stamps have no importance at all).
- Nr 0 ( not shown) has a perfect centering on both directions. Let's give it a grading of 100 %
- Nr 1 (left) is slightly shifted left . Vertically it is OK. The perforations on the left side do not touch the design.
- Nr 2 (middle) is heavily shifted left and slightly up . The perforations on the left side cut a little bit the design.
- Nr 3(right) is heavily shifted right and up. The perforations on the right & down sides cut a little bit the design.
In your opinion, how do you grade these stamps, compared to the Nr 0 ? ( answer in %).
Please give some explanations of your evaluations.
Do not take any other faults into consideration ! We are discussing only about centering.
Thank you for your participation.
