A New 1338 Imperf Variety??

More scrap finds. These might or might not all be from the same sheet. I know there are 1338 sheets imperf at the margin, but I've never seen one imperf in multiple places...

It looks like an equipment malfunction. Maybe these are better described as mis-perf freaks rather than imperf.

votehannibal...these are NOT imperfs.
Just missing a few perf holes. Very common on this issue.
I have seen the entire side imperf.....with 0 perf holes....
and barely sells at a premium.
Think I sold a Plate block....FULLY imperf @ right for like $10....
Probably can search eBay sold items and see.

This is commonly called 'blind perforations' and is fairly common when billions of stamps are printed

Now that's interesting. I thought "blind perfs" refers to imperfectly punched holes, not entirely absent holes.

It is. And from here it looks like much more blind than missing perfs.

Peter

There are some blind perfs in your block. That said, there also might be some completely missing perfs. One would need to have the item in hand & carefully scrutinize it under high magnification to discern whether this is the case. You need to realize that any indication at all of a perforation, even the slightest indentation, counts as a blind perf. In any event, your block would be, at best, considered only partially imperforate … and therefore, given that imperfs are common for this issue, of little monetary value. A similar "rule" applies to missing color and tagging omitted errors. Any evidence at all of a color or tagging, no matter how slight, marks the item as a freak rather than an error.

Oh, they are definitely missing entirely in many spots.

even a single perf hole or indentation disqualifies it as an imperf and moves it into the freak category

About the staple (?) holes in the margin, I've seen them on many issues of that era. Are those holes indeed from staples? If so, what had the pane been stapled to?

perf10...the staple holes are where the sheets were "stapled" together in a bundle....unlike later when wrapped in plastic in lots.

sheetguy2, thanks.

Would love to know more about that, but I find nothing online. For example, were the bundles usually of 10, 50, 100, or X panes? Were they bundled for shipment to particular post offices? For example, post office A gets a bundle of 100, while smaller post office B gets a bundle of 10. I don't recall ever seeing such bundles at a post office front counter, so perhaps they were separated before reaching the clerks.
