199? DDO On Liberty?

Ok thanks-there's something real strange going on in 'liberty' but it's hard to get a good pic of it but I'm trying-almost can see a backward 'R' also?

The LIBERTY is showing Die Deterioration. This appears toward the rim of the coin. On LIBERTY you will see it on the left side, on the date you will see it on the right side and the motto you will see it on the tops of the devices. As mentioned the area of the date was struck through a grease filled area of the die, not allowing the full date to appear. Interesting but not a big premium for this.

Correct. That is not actually doubling, but die wear that takes off the edge of the die toward the rim. When the die wears away, (Negative) the coins (Positive) show the indentation on the die as a raised area. Die wear on the single squeeze dies look differently than the multi-hubbed dies that were used years ago. Here is an example of what the die wear looked like back then:


With the single squeeze dies they now start to look like this:


The lower profile of the devices, shows wear differently.

Yes, you will see it all over the place on coins struck with over polished dies and worn dies.

The more I look at the comparisons you guys send the more I'm starting to get it and see the difference-not easy tho! Lol...I'm I right in assuming on true DDO and DDR's that both images will be of the same shade also? Like in mine I notice the secondary effect I think I'm seeing is of a lighter shade but in your examples of true double die's I see both images are the same shade or is that irrelevant?

Shading doesn't have much to do with it all. Its more of height and clarity. DDO's and DDR's the stampings should look close to the same.
On minor variations, there will be "added thickness", but for some that phrase is over-abused and not a definitive explanation of what is going on with that particular die that hammers the coin.

John Wexler ( http://doubleddie.com/ ) has an excellent site on how determine the difference between a true doubled die ( DDO or DDR), and the worthless Mechanical Doubling (MD).

Another site that shows som DDO vs. MD comparison is here;

An important thing to remember about all this is;

Doubled dies should ADD to the overall size of the devices, typicaly at the same height or close to it.

Machine Doubling will reduce the overall size of the devices. Typically the letters are cut down, and some areas may look flat.

Dies that hammer the coins will age and wear down. The older the die, the more likely that Machine Doubling will occur.

Gary, I forgot to add the link, but the one you linked to is the page I was on..
