Is it possible to have on one letter DBL die instead of a whole word? 1993 P Quarter

Is it possible to have on one letter doubled die instead od a whole word? 1993 P Quarter

I read this: "Strike doubling can affect all lettering on one or both sides, or could be detected on only one letter or a small portion of a device." The "U" on the Reverse of the Quarter in UNUM looks to be a DD but I'm new and could be mistaken.

What are your thoughts?

Thanks in advance.

In my opinion, it's more possible to have a case of isolated machine doubling than a single letter doubled die. Here is the reason why. If there is much separation in a supposed doubled die, there should be more than one device ( letter, number or other raised area of the coin) doubled.

Doubled dies are exactly what it sounds like. Ita one impression over the other. Doubled dies have a region on the coin the doubled die is typically are stronger on, and other areas may not show any doubling at all. It depends on the severity.... how far off the axis is, the higher degree, the more potential for more devices to show the doubled die.

When Doubled dies are created by mistake, its typically impressed onto a working die. They use the same tonnage of pressure to create these impressions, so they should be at the same height when you see them on a coin that working die made.

The coin pictured above has a step like look to it, or shelf like appearance. This means it's at two different heights. Machines are not perfect, and neither are us humans. Variables happen when these over zealous minting presses strike billions of coins each year. Add in that the dies made of metal stike hundreds of thousands of coins too. These working dies lose their sharpness and luster over time, and are subject to becoming a tad bit loose compared to a brand new die. These impairment can introduce minute issues which can cause theminting press to create machine induced doubling, like mechanical. Machine, strike, ejection or other type of worthless doubling.

To me, in my opinion, since this has that lower, step like or shelf like appearance, this is known as worthless doubling, mainly due to these conditions happening so much. There is no notching or split serifs, and no hint of a cookie cutter style line which shows where one impression is o top on of the other impression.

I think you could probably see 1000 worthless doubling coins before you find a bonefide doubled die. The ratio may be a stretch, but not by much now a days.

I've learned so much from your response. I now trult feel I cn tell the difference in the future much like the small nuance in the 1969 S Doubling on the cent or the very clear doubling in the 1955 Lincoln cent. I now have an understanding of "slippage" when can cause the machine doubling and cause clean clear shelf-like appearances. Thank you MintErrors ~Ronnie
