Interesting. What do you think it is? It looks like it starts at the bottom, and is a very straight line, up through the left eye, but not to the very top.

I believe that these were recess printed therefore most logical explanation is a ductor blade flaw.

You also have "Type A"

The line that bisects the bottom loop of the "5" has 4 lines below it.

Type B has 5 lines below it.

Also looks like Her Maj has had her jawline retouched...?

Rod, thank you for the additional supporting information. I hadn't seen the Q20 Fracture description before, so I'll have to look for that in my others.

I've been looking, in my squillions of this common stamp.
No luck as yet.

I am wondering. If it is a Doctor Blade, is there any reason why the line starts exactly at the bottom of the design of the stamp and continues only partway up? The example from Rod seems to start at the very edges, is not quite straight, and continues through two stamps completely. Just wondering. To me, it almost looks like an incomplete guide line, but I'll await more comments.

I share your curiosity, that is why I did not answer immediately you posted the query.

"Doctor blade" covers most lines through stamps, but your line ended abruptly
at the stamp design margin, at the bottom, that rang alarm bells.

I have no other suggestions, and await your findings, if any.

There are, in general, two types of ductor blade flaw. One caused by damage to the edge of the blade which will traverse the full stamp design and be a feature of many stamps until the blade is replaced. The other type is caused by foreign matter adhering to the edge of the blade in which case the length of the flaw will be determined by how long the foreign material is present.

Here is one of the latter which I copied off the internet to demonstrate that not all flaws traverse the full width of the stamp

Thanks to Frank for another great example. One last question. Is it Doctor or Ductor? Thanks in advance.

Ductor is the original spelling. I use this form as when I worked in a laboratory on research into paints for printing, I used a ductor blade practically everyday on hundreds of experimental samples. Somehow it became corrupted over the years.
