    Sometimes strike or mechanical doubling is confusing, but here are a couple of easy-to-tell examples.

    Sooo. Can you maybe explain which one is which, and why?

    give the guy a break....i am sure that there at least a few people out there who will read this post not having ever heard of doubling or knowing it to be a type of error coin that they could look for.....helping out the newbs is an important job as we were all there at some point....

    I agree. I love learning more about the difference from MD and DD, but this post doesn't give it.

    True... but posting a few photos without explanation or comparison photos of true doubled dies is counterproductive to someone trying to learn the difference. What makes these strike doubling? How does it occur? What is true doubling, and how does that occur? This is the info I need to accompany the photos in order to LEARN.

    True doubled dies tend to show a rounding of the doubled area. The doubled part tends to look more like the form of the original number, or whatever is doubled.

    Strike doubling creates shelving, or flat doubling, so that the doubled part looks like a flat shelf or stair.

    Then there is degeneration doubling which basically results from the dies getting old.

    Strike doubling and degeneration doubling are not true doubled dies, and are usually not worth more than face value due to the "doubling".

    To be honest, the pictures you show, to me, aren't easy to tell examples. The doubled area looks slightly rounded to me, and although they are probably strike doubling, I for one couldn't tell that 100% from looking at them. I have however, seen much easier to tell examples.

    The denver mintmark in the top photo does appear to be strike doubling to me. But the rest, just looking at the photos, seems hard to tell.

    The original post was like trying teaching us how to tell the difference between apples and oranges but showing us only an apple.

    Am I admitting that the emperor has no clothing, or does everyone else think that these photos show obvious strike doubling. Because to me they are not obvious. Maybe in person they would be, but from these photos, I couldn't make the call 100% on both those photos. Not that I'm an expert.

    I guess I was giving too much credit to the audience here. I was simply posting photos of two coins that I thought had unusually obvious strike doubling. I didn't want to be preachy. I will assume less prior knowledge in future posts.

    Good idea. As far as I know, there are only a handful of mind readers here.
