I have looked over the whole sheets available through this site and found a few small spots that might be useful for identifying position A53/53 on printings between 4 øre printing 1 and 3 øre printing 1. They are circled in the images below.
4 øre printing 1:

8 øre printing 1:

16 øre printing 1:

25 øre printing 1 only has one of the spots clearly visible:

On 12 øre printing 1, two of the spots are clearly visible

One 3 øre printing 1 only one of the spots are clearly visible:

Hope this is useful.
Best regards
