1944 Penny Coast To Coast Die Crack?

Looks more lie a lamination line. Is this a proof coin, or a plated coin?

I'm thinking lamination. Yes, that coin looks cleaned/burnished, possibly plated. Better photos may tell the tale.

Images need to be sharper and the coin lit from a slight angle.

Just can't tell from the pictures, new picture is washed out from the glare.....

Last photo was sharp (others above were not), but light and contrast way too off. I agree, coin looks cleaned/polished and now holds very little numismatic value. If you did this, let it be a lesson to you: Never clean your coins. Never.

Sorry for the confusion on this post new to this.

I agree the coin has little value. I got this "American Heritage WW II Coin collection" for .50 at a garage sale. It had a 1935 P silver nickel in it (highly polished as well) and a couple of Wheat cents and a rusted steal penny. I noticed the damage through the plastic and opened it. I'm trying to learn and this seemed like a good coin to do that on.

When I saw the damage my first instinct was lamination error. Then looking at I see there are raised sections running over the top of the raised portions of the coin. Like the "O" in ONE and through the other lettering as well as over the wheat stock.

My question would be if this is a lamination issue would the act of pressing the planchet in the dies made the transition over the "O" smooth not raised as it is?

Assuming you mean 1945-P, the silver alone pays for the whole lot nearly three times over. Well done.

Hey NickG, I'm in agreement with Numisma on the question about you possibly mistakenly typing "1935 P" Nickel but meant to type "1945 P" Nickel. A 1935 (P) would be a Buffalo nickel and NOT exhibit a P mint mark. A 1945 P Jefferson nickel would have the P mint mark and WOULD contain 35% silver whereas a Buffalo nickel would not have silver content I believe. Just thought I'd bring this to your attention in case it was a typo my friend.
Also...... I am NO expert on laminations and have beat myself up over die cracks in the past, but, regarding your 1944 Lincoln I do see something in your last reverse pic that I thought I'd throw out here for the experts in case it was overlooked. At the 11 and 5 o'clock positions on the reverse there seems to be an intrusion of sorts into, or on, the rim of the coin. The entire circumference of the rim on your cent appears to be intact and uniform until you get to these two locations on the coin respectfully. It looks like there are visible indentations at the 11 and 5 o'clock locations where the "whatever it is line" is intersecting the rim. Just food for thought and didn't know if this may be of interest to others. Not sure.......
EDIT- HA! our posts overlapped on your comment of "fat finger".... lol. I'll still leave my comment as is.
