Hi Wb,
I've seen a few Machin stamps cut like this green one.
This is is caused by the teeth of a stamp machine not lining up with the perforation holes of the stamps in a coil and these teeth end up cutting the stamp as on the left side of your stamp.
The stamp on the left is Guatemala Scott# 300 which is Scott# 235 perforated diagonally through the center.
So Nigel, the Machin isn't a bisect, but rather an error during the perforating process?
Thanks Dakota, it looks like it may be the only true bisect I have.
I appreciate the info,
WB

Very good, thank you for the help.

The vending machine coil miscuts happen in the US as well. Or should I say, mis-tears. Sometimes the customer tugs too early on the coil strip as it's being dispensed and knocks the roll off-alignment. But on the US coils, the serrated edge is finer, so it doesn't produce anything as close to the psuedo-perforations shown on the Machin.
In the early years of the experimental/limited-availability computer vended coil machines, some collectors would deliberately tug, trying to cause the printing of the stamp value to be shifted and creating an EFO. Unfortunately, the result was the machines went off-line a lot, leaving a lot of annoyed collectors who made a special trip to those select few post offices.
Your conversation reminded me of this stamp from my collection that appears to have come from some sort of stamp vending machine. The machine's cutting blade was slightly off from the stamp's perfs, probably from someone pulling on the stamp as it came out of the machine.

It is a error of distribution, not production. Interesting when mounted alongside the strips of multi value Machins, adding a discussion point to the collection. I.d love to get one so close to being torn in half.
If I understand USPS rules it would be invalid for postage. I'm not sure if RM would let it pass through the mail stream.
The deliberate tugging of collectors on the computer vended postage would be a production EFO, since they were trying to get the machine to shift the printing of the denomination. The coil rolls were originally delivered to the machine as blank denominations.
The ones caused by the coil vending machines being off-alignment would be, as cdj1122 pointed out, caused by the dispensing process. The actual stamp print is normal, since production was completed prior to delivery to the vending machine.
Man vs. machine, I love it! It always amazes me what some collectors will do to try and shift the tide.

In my summers in Germany decades ago, I often visited post offices. At all clerk stations there were coils contained in metal cases (looked like film cases). When stamps were purchased, the clerks would manually pull stamps from the rolls. Many times, the stamps were incompletely pulled and torn off the roll leaving similar jagged cut marks or tears as Linus showed with the KGV coil stamp. I see these stamps now and then in German accumulations.
Not an area I'm very familiar with, but have seen a couple of recent posts on the subject and thought I'd ask about these.
The main thing I was wondering about, are the perforated cuts. Most examples I've seen are straight cuts. Were these cut at the P.O. or by a second party after purchased?
Any other info would be appreciated also.
Thanks,
Wb
