....what type of doubling this is. I'm almost 100% positive it isn't 'shelf', or mechanical doubling....it's spread throughout PLURIBUS UNUM, and on the letters IN GO of IGWT (couldn't get images of that part of the coin...I think those of you who have seen my images know I can barely use a point n' shoot), but I was able to get enough of the PLURIBUS UNUM to show the doubling clearly enough. I have another image that shows the UNU better than in this accompanying image, but thought this was enough to give a good representation to make a judgement call. It's on a coin where there are no varieties in the CPG, the CONECA website, nowhere...any help/suggestions??? Thanks!

It is shelf doubling.
The shelf almost eliminated the normal lower edge of the loop of the P.
A doubled die doesn't take a shelf out of the normal design, it adds to it.

I can see how it looked promising the way it shows on the B but it is shelf doubling.

I personally thought the U's look more promising..but I do agree with the shelf doubling.

It almost has split serifs on the R and I... but it is shelf doubling... Cheers, RickO

I think the proper term is "machine doubling". No added value.

Thanks all. Like ricko and InternetJunky said, the serifs on those particular letters had my blood pumping a bit, which is why I came to you good folk for another schooling.That's why you guys/gals are the best. Thanks for your help!!

Being lazy and not referring to our hosts glossary, could someone explain "shelf doubling" to us uninformed?

Here is an image of a 1969-S Lincoln Cent with Mechanical (shelf) doubling.

The dies bounce when they strike the coin. The bounce causes the second image to flatten out some of the original image leaving a flat shelf. Note how even the mint mark is flattened. You can see a bunch of double dies on my link below which is a nice resource when making a determination on some of the varieties.

Also notice how deceptive the number one in the date is. It really looks like a split, but it is just a flat area.

I would also say this coin could (stress on could) be a double die with strike doubling. Take a look at both letter U and you can see a split in the upper right upright (top). It appears to have the strike doubling on the bottom of the letters. I think it would need to be examined in hand for a final determination, but I do think it "could" be a double die.

Here is a true double die with a nice spread.

Here's a link to Wexler's site that explains shelf doubling and other worthless forms of doubling.
