I Would Like Some Help With This Block Of The 3 Cent Nebraska Overprint 672

I acquired this block some 40+ years ago ian accumulation of Kans/Nebr overprints. It was marked as missing a period after Nebr on the right side two stamps.

Any thoughts on this?

Have you checked the gum breakers on the reverse? Scan please.

I have checked the gum breakers on the reverse. There is on breaker on each stamp. attached is a scan of the back. The breakers are hard to see on it though.



2nd image is taken at an angle trying to show gum breakers.

Looks good; one gumbreaker per stamp plus the vertical breakers.

The attached two images are magnified images of the areas where the period should be after Nebr.

Now that the more experienced collectors on this forum have had a chance to look at this posting, I would like to pose a few questions to them.

Do you think that this is a genuine Nebraska overprint without a period after Nebr in the right two stamps?

If you think it is genuine, any idea as to value since this variety is currently not listed in Scott Catalog and it comes up only every few years at auction.

Do you think I should go through the expense of having this expertized?

If you think this item is not genuine could you please share why with me so that I can learn more about this.

Thanks in advance for your help and insights.

I cannot see a period on one of the stamps but Retroreveal show a very good potential on the other.

If you mean that the lower picture of the two has the potential of a period, I believe what I am seeing in the reveal photo is too low for where the period should be on a normal stamp. I am attaching a closeup of the Nebr. with period from the top left of the block to make the point.
You can see that the bottom of the period is level with the bottom of Nebr

I see you point. I looked at some on Seigel and found one where most on the block also appeared to have no period. It wasn't mentioned in the sale info though.

Bottom scanned stamp clearly has a period to the left of the numeral. I suspect that the top one does as well; probably it would be visible under the VSE6000 is it was sent to be expertised.

After revcollectors post I went and checked the block again and found I had inadveretantly uploaded the wrong image for the bottom stamp. Attached is the correct image for the bottom right stamp. My apologies to the forum.

Caper123 if you could be so kind as to do your retrofeel on the last stamp I posted it would be helpful.

adamscheer - running the last pic you supplied it almost appears as if the 'period' was once there. There is a shadow of it where it should be. Not sure what that means but it's possible it was removed somehow.

ps - th
e last picture you supplied is the same as one of them before.

I have seen no period offered before, but am not so sure they are a recognized variety - I don't think there was a position on the plate where the period was missing, rather this was just a case of the period not inking. Also it is hard to see a small partial black period on a dark violet background.

Caper123. Sorry abou the confusion. I had to use the tool online here to reduce the size of the pictures to below the 200KB limit and in the process got my pictures mixed up.

eyteonw3all. The variety has been rocognized before as there have been several certifcations issued by the expertizing services and the stamps have shown up in a number of auctions by Harmer and others.

So I will take another look at the picrues tomorrow and see if I should repost here before deciding what to do. Thanks for the help so far.
