My first thought was Machine Doubling or even tripling. But since the date and mint mark are affected it could be a DDO. Can you post a photo of the whole coin?

I'm going through a few boxes of these... *yawn*. Nice to see someone find something even if it's only MD.

Can someone point me to a link which explains Machine Doubling? Here are a few more pictures of the coin. I don't see what is "plating issues", but I'm new to this whole close up world of coins. The coin is a very appealing red copper color, but with the bright lights of my USB microscope it's color is not true. I have included a whole coin pix from my Digital SLR and Macro lens
Thanks,

Look at the S and notice that the underlying S is not complete (in the curves). If this were hub doubling it would be complete and crisp. Also the top S is distorted and twisted looking. Again it would not be that way if it was hub doubling.

Besides all that, single-squeeze hubbing is supposed to stop true hub doubling like the famous 55.

Good point on the "S"
That would convince me it would be MD then.
Was thinking, if just a single squeeze then if MD is showing up would that most likely be a collar issue or MAD ?
It's not like the die would be bouncing around on a one shot deal.

Two entirely different things here. "Single squeeze" refers to the hubbing process, i.e. the creation of the die. MD is caused by movement of the die during the striking of the coin. Even though business strikes are only struck once, there can still be slight movement of the die.

I don't know, but it looks raised to me. Hard to tell from a pic.

Die wear flows toward the rim. The direction of all these areas in question are all toward the rim. but can die wear also show on a real doubled die? Here is a set of images and note how the date shows die wear as well, but note how much stronger the doubled die is than the die wear:

So I feel this is just die wear.

but not in different dirctions at the same time. Look at the direction of the "doubling" on the mintmark and on the S in TRUST. In both cases it is "doubled" out toward the edge along a line from the center of the coin, through the doubling, to the rim. Now the die can't move both ways at once, but die wear and die wear doubling does radiate out from the center towards the rim.

Thanks all for the links and the feedback. I have lots to read and try to digest now. I will post other "finds" as I continue to examine my collection in more minute detail. So what I am reading is that the Machine Doubling type errors are not all that rare and do not bring a premium. So all said if I was to put this coin on auction what could I expect? The way I'm reading it is that I would have to charge shipping to bring myself near even.
Thanks again.

Machine Doubling is not an error at all, it is just a normal part of the minting process as are die cracks and chips.
