United States/Stamps : 633 pre-canceled sequential plate blocks

I decided to start this thread because these two plate blocks deserve the honorable mention. But would fit nicely in several categories of existing threads.

These almost got past me and are from the same 22 pound box lot that I have been working on sorting to keep what I want. They are 633 plate blocks pre canceled for San Diego Ca. They are in sequential order and the higher numbered plate block has evidence of a double transfer and the lower numbered plate block does not. They both have original gum and have not been hinged. There is fugitive ink transferred in the gum on both plate blocks that likely took place in the drying and stacking process after they were pre-canceled. Pictures of the back are on the way. The double transfer is circled.

Technically they are used because of the pre cancel but show absolutely no evidence of ever being affixed to a piece of mail. Because the gum shows the breaker bar gripper cracks as they are rotary press printings.

This begs the question. Have any of these been reported as used? Because the catalog lists plate blocks of 4 unused but a dash for the used category. The double transfer changes the game too.

re: 633 pre-canceled sequential plate blocks

These 2 plate blocks have been bugging me to no end. For a couple of reasons. One I am not a plate block collector and two I generally don't collect pre-cancels. I can and will make an exception for these of course. Because they are in numerical/sequential order and one of the stamps in the higher numbered plate block has a double transfer.

Now here is my biggest question. How do I characterize them?

I know technically that they are used.

But the fact that they were never affixed to any form of postal media/letter or package and they clearly have original gum in never hinged condition. Doesn't that change the game?

What is even more puzzling to me Scott only lists and places a value for a #633 plate block in unused condition and has a dash where a value would be listed for a used plate block. So in my mind they do exist just not enough plate blocks have been reported in used condition. So to place a value would be a futile effort at this point.

I'd like to learn more before I leap into the deep end of the pool.



Perhaps one of our SOR members who specializes in pre-cancels could give us some insight?

Jeremy,

scott doesn't value PBs in used condition, only mint (MH and MNH).

Pre-cancelled stamps and their cousins, service-inscribed stamps, are typically considered used, regardless of either gum or their use in moving the mail. I'm guessing the "cancelled" part of pre-cancelled is a good clue.

I was SHOCKED to see the value for a 633 PB, and more for a MNH PB. Wonder if anyone pays that freight

amsd,

What you have said is exactly what I was thinking to and I was as shocked as you are when I saw the same thing in my 2025 US specialized. It is pleasant to find that someone else is or was thinking the same thing.
