I was curious after looking at the new post for this coin. How can you differentiate what may be die chip from doubling? When I looked at this one I had difficulty exactly matching the doubling of the index finger to the shape of the index finger and then I wondered about the possbility of a die chip vs. doubling as a possible explanation. Probably off base but curious.

A die chip is going to have a very irregular shape and will be very sharp and jagged around the edges. Hub doubling has more regular edges and blends into the field around it. Hub doubling is also 'matched' to other details on the coin in some form or fashion, but what you have to remember is that hub doubling will show itself working from the top down. Here's what I mean...

When you see an alligator in water you generally only see its snout and eyes. Doesn't mean ther est of the gator isn't there, you just can't see it. Now imagine the gator half way out of the water. You can now see some of the shape of its back and tail, and the head/snout will be "connected". When the gator comes all the way out of the water, it looks bigger than ever, and you can see its whole body.

Much the same is hub doubling. When something like the finger is hubbed lightly into the die, you see the top ridge area of the finger only. The heavier it is hubbed, the larger and more defined the finger becomes. Think of it that way, go back and look at the images again, and I think you'll be able to sum it up for yourself.
