Welcome aboard Wally:)
That cent was a normal cent then someone filed the reverse side to be flat.

Wally W, I agree. The "proof of the pudding", is to weigh it. It should weigh 2.5 grams, because it is a "zincoln". Welcome aboard! Pull up a cactus, and sit for a spell!

Keep looking, the next odd coin you find might be a keeper

How did they know that is what happened? Besides the missing copper plating on the reverse, there is also a rim that is added to the make it a planchet after the blank is run through the upset mill. The blank is rolled into a smaller area and forces the rim to form. If you have a planchet that is not struck yet, then you would know what I mean. On the obverse the rim on the outside edge of the coin flows upward toward the rim. The reverse has no rim, thus it has been removed.

Coop,
That's great!
I wanted to explain the reasoning but didn't want to write a book. Your pics show what I was thinking in a few pics.

ok i have a quick question.. I have been told that it is impossible to have a coin with a blank reverse while showing a portrait on the obverse is this true? and if so i would like an explanation to better help me understand it. I was told this about a year ago and i cant remember what the people said. I say all that to say that i know a guy who said he sent one to a TPG and it came back authentic

Here's my guess 
One way might be a blank planchet is in position and in collar and a second planchet gets fed directly on top of it then they both get struck. (a zincoln sandwich) The bottom coin is in collar and uniface and the top coin is probably out of collar and uniface.
LOL...

With the same stated scenario, wouldn't the top planchet actually be a brockage" Just curious,
Dick

Dick,
Yes, I think in that scenario if the lower coin was already struck then the second coin would have brockage. (a negative image of the lower coin)
If the lower one was a blank planchet then they would both have one blank side without brockage.
It's also possible that both were already struck then struck again or if that top out of collar coin sticks to the hammer die it becomes a "die cap" and if it strikes a lower coin then that coin becomes a "struck through a die cap".
The closest thing to these that I have is this coin, it's off center but the reverse has part of the memorial then the obverse has a brockage from another coins reverse.

Ed, I have a set of progressive off-center cents, that go from a palnchet, to thenearly full strike position. All have both sides struck, except for one, which barely was hit, and has no design on either face. I think I posted them, recently I have gotten blank planchets, but this set was bought on ebay, as a curiosity item. I save die breaks that are also progressive in the same position, Those are on the state quarters, mostly.
The brockage was something I was not sure of. I hadn't considered the "die-cap" aspect. Youers look like they were stuck, or jammed, and couildn't move, getting a multiple strike. look at the bottom one.
Dick

Dick,
Can you see how the one side has brockage, it's a mirror image of the reverse of the coin below it.
Both pics are the same coin, one side is a reverse and the other side is a brockage reverse.
I think this coin was the top coin and the one below it was already struck then struck through this one (which was blank)laying partly over it.

Your information is incorrect. There are several avenues that lead to a normal-diameter coin with one face fully struck and the other featureless.
1. An in-collar uniface strike, a.k.a. full indent. Two planchets are stacked on top of each other in a common collar and then struck. Each coin has a struck face (one the obverse, the other the reverse) and the opposite face is blank. The blank surface is not mirror-flat, however. There are at least slight undulations of the surface. A surface flat as a pane of glass is a dead giveaway that the coin's been altered.
2. One die fully obstructed by "grease" and the other die with no accumulation of grease.
3. Coin struck by an early-stage, uniface die cap. Usually there's still slight bleed-through of a ghost image.
4. One face completely obscured by foreign material a "strike-through" error. Usually there's an odd texture.
