1939 Football Cancel

I know Football cancel is not the correct lingo. Could someone please let me know what these are called? Also, I was wondering how early did the U.S. start using these? Were they used all over the U.S.?

That is part of the duplex (two part) cancellation (cancel) called (I think, may need correction) the obliterator part or obliteration (used to obliterate the value of the stamp so it cannot be used again and I would call it an ellipsoid numeral cancel. I have heard that term before. (Mostly on Canadian stamps, me not being too much into US stamps as of yet, it looks similar.

The circular cancel part is the Circular Date Stamp (CDS) or Circular Date Cancel (CDC) some say par of the duplex cancellation.

Oh, and I like those misperfed Jefferson's. I like misperfs!

Thanks for the info. What do you mean by misperf?

Misperf is an abbreviation of Mis-perforation, a mistake made when running the sheet of stamps through the perforating machine.

The design of the stamp seems to be moved away from center (and sometimes over the edge) because the perforations (perfs) are not punched out or cut correctly. Yours are not really dramatic but noticeable. Some mis-perfs are more noticable where the design of the next stamp(s) is/are noticeable on the one stamp.

Examples:

I'm not sure what the official termology or purpose is for those cancellations. I have seen them with several different numerals though.

I have always referred to them as "footprint" cancels,
as a broad classification, but I am not sure where I read that.
Certainly found generally as a duplex, but sometimes found
singularly.
My collection includes numbers 1-2-4-6-11-14-19, a mute, "P"
and "RMS" on US strikes.
The term "footprint" may have been coined after the moonwalk
as seen on this czech stamp.

The postmarks in the first pictures are called barrel duplexes. If the "football" is just a series of bars then it is called an ovate bar duplex. There's also a third version where the year is printed between the CDS and barred oval and sometimes I'll see them referred to Triplex postamps, but I think that term is less common. I don't think the Jefferson Prexies are misperf, but two pairs from a booklet pane with some overlap.

A good quick reference guide for early 20th Century postmarks - "Postmarks on Postcards" by Reichard W. Helbock.

Hi Puzzler.....


The Jefferson's are not mis-perfs......they're a mix of booklet & sheet stamps.


And, you're right.....it is an ellipsoid.

Good terminology by all. Nice to learn new terms.

The second two Jefferson's (sheet stamps) seem to me to be misperfed vertically because the design overlaps the top edge (perfs) of the stamps.

Perhaps to be a more obvious misperf would be better, but I do tend to look for these and notice even a little bit of off-centeredness, just as we all are susceptible to the you-see-what-you-want-to-see problem.
