After finding this DDR, I got interested in the extent of doubling present. Of all the doubled dies I've found, I think it's the largest in terms of area affected on the coin. Since I have not seen this done before, I decided to colorize the areas affected by doubling. This took some careful study, comparing my coin to normal reverses and applying to a photo of an MS coin. No doubt, this doesn't represent all the doubling present on the coin; it's only what I can detect. The doubling affects 80% of the width of the reverse and 62% of the height.

Note--if you click on the image, it will expand to view the details better--I think it's pretty interesting for study.

That's a nice (and useful) image-thanks for posting it! I don't want to get too technical but it's unusual in that it's listed as a Class I (rotated die) but, more like a typical Class IV (offset die) it hubbed up mainly toward the center of the die.

I mentioned in an earlier post about how important die state is, especially as applied to doubled dies. This 1946 Walker is one issue where die state is critical, especially on the motto, and IS taken into account. The coin you show looks to be a fairly early die state.

Thanks! I used a high-grade pic of the DDR with a high amount of detail so I could call out all the doubling.

.I've given it some thought and tried to reproduce the doubling using Photoshop. I can't reproduce it with a simple rotation--there must be an offset too.
