Kansas Nebraska Overprints Of 1929 With Missing Period

So I notice that just the Scott 669 1 cent Nebr. is the only overprint with missing period. Didn't they use the same overprint plates on all the stamp values? So why doesn't the missing period overprint show up on the other values?

Something could have been stuck to the period on the plate, keeping it from printing for a spell

Is that what caused the Nebr. overprint with the missing period? I never heard that.

Repairs happen.

So for over 40 years it was a fact that none of these overprints were without a period. I even own this stamp but received a negative certificate from APS back in the 90s because the experts on this said none were printed that way. Now it comes to light that 2 places did occur without a period and is listed as a true error. Can we expect other overprints missing a period to come to light on other values?

Resubmit the stamp and certificate.

Edit:

As knowledge increases, listings come and go. Now quite new compared to yours, but the Overrun Countries took a long time for the reverse printings to be accepted.

I see the The American Plate Number Single Society shows an unlisted 3 cent kans with no period.

I'm not worried about my stamp I'm just asking a question, couldn't there be others on the other values? I don't belive something stuck to the plate caused this issue. more like the plate was damaged.

The expertizing committee may do the fix for free. But the reason I suggested the recertification is to get the only and now clearly wrong cert out of the data base as suggesting the missing period copies are fake. I say this trusting yours is not a tampered stamp where someone removed the dot.

Petert4522, Scott catalog listings are only made for constant errors and not inconstant ones.

Aye, and there's the rub, or at least part of it. Skip the following if it's tl;dr. If it ain't in Scott, it basically don't exist. US Scott 6b, the 1c type Ic wasn't listed in Scott until the 1990s. The type was known and so identified in the ancient Ashbrook 1c books. But certs I've found up until then identified them only as type III/IIIas (maaaaaybe type Ia if you were lucky), both with and without the position given (you have to ask for position confirmation). And the experts examining these and passing judgement were the 1c experts of the time. Specialists and Mortimer knew what type 1c was, but prices were low with no value established and little competition for the type.

So, yes, there are probably more of the no stop/period examples out there that are genuine errors. Meanwhile, I've seen a couple that had uninked stops/periods with a clear dent in the paper where it should have been. Still, someone has to research it and then lay the proof at the feet of Scott Publishing.

OK folks, I just gave a possibility as to what could cause a missing dot. I never said that it is that way!

Petert4522, I didn't take it that way. As noted above, there are cases where the stop/period didn't print due to inking problems. But those don't count as true errors.

So again, 1. what created this error. under-inking? damaged plate? something else? 2. if it was a damaged plate and the same plates were used for the other values, should there be a possibility that it occurred on them? Or was it caught when doing the 1 cent overprinting, the first value done,(we are assuming) and repaired before the plates were used on other values?

Hy-brasil, I thought one of the ways to identify fakes was from the impression it made? My understanding is the real overprint did not make an indentation. I will review my book on this again.

Genuine overprints have gum with only one gum breaker and striated ridges.

No indentation means likely a spray on overprint (fraud).
Uneven indentation likely means typewriter (keys) used to make over print (fraud).

The genuine overprints were surface printed, so they had no indentations. The 3 cent stamps that I have seen with a "missing period" appeared due to under inking; with a very strong glass (40X) some black was visible.
