What do the experts think of these halos?

In my opinion, the halos seem to extend to the right of the "7"; the "0"; and the "3"

If a person were right handed and applying something to the metal to remove the blue and create the impression of a halo, they may have started with the first number, perhaps using a cotton "Q-Tip" and dabbed something on each of these first three numbers. This could explain why the three halos on each of these first three numbers tend to expand to the right side of each of the three numbers. In other words, the fluid would have followed the "Q-Tip" from left to right.

Now look at the last number, the number "1"

It has a halo, but notice that the bottom of the number "1" has no halo at all showing in the photograph. How could the bottom of the number "1" have somehow avoided showing any halo? Or is this just the way the light is shining in the picture?

Or am I just being overly suspicious?
