I have a plate block (Scott's US 1050 40 cent John Marshall). In looking up its value, I found the same stamp with the same sheet number but in a different position. Here it is on Amazon:
https://www.amazon.com/1958-JOHN-MARSHALL-JUSTICE-Postage/dp/B003LG46FK?tag=treasurenet01-20
My PB # is on the outside top left.
The stamp has no varieties so I'm wondering why the same stamp would have duplicate sheet numbers?
I'm old enough to have forgotten the answer 60 (or 70) years ago, so please be kind with your response.

In the link below scroll down to see the sheet made for the John Harding stamp. Also read the caption underneath. Looks like some plates had multiple sheets with the same plate number but positioned in different corners.

Thank you NJearthman !!
Apparently, the plate block being sold on Amazon came from the same sheet as the one I bought in '58 with the same plate number.
That would certainly be coincidental.
