Error Struck Through | 1990 Struck through grease with striations

[VAB2013]

Pretty sure it's a Philly with a big thumb print on the obverse. In hand the heaviest striations look frosted and where they are at the top of Lincoln's hair the coin looks flattened and smooth.

It was fun to look through these greasers I haven't seen in awhile! All of them have striations. Before I put them away I took pics of this 1991... here it is.

Very cool coins and pics Viv!! There's a lot going on with that 90!!

Viv, you are good!

I bet most people would think it was a 1999 WAM and go off celebrating but you are right, it is a 1990.

Thank you Jon and Ed! I wonder if during production, the dies are constantly being fed some grease to keep things running smoothly and sometimes that goes wacky. Like maybe when the grease apparatus has to be refilled (or there's a malfunction in the machinery) a bunch of the grease gets released onto the dies and that's what causes the extreme greasers and then it gradually clears up when the grease returns to a normal drip? And as a result of the grease, it is the reduction of striking pressure that causes those lines? Could it be that this is the same thing that we see on the reverse at EPU and TATES OF when that area is flattened and there are lines? I can't help but see the similarity in these lines on greasers and the lines we are seeing on Memorials and Shields where there are not as many lines and the devices look somewhat flattened. I am anxiously awaiting the moment when Will can talk about this with us! Grease is the word!

Now you're getting the idea! This is one part of it.

Thank you Will! I still have so many questions... but I will wait patiently and remain anxious to hear about your study! Now that's an oxymoron!

Nice find Vivien... What about the rev close ups... Looks like lots of stuff going on back there???

Thank you Jim! I really don't know LOL! I looked at the reverse and nothing really jumped out at me, let me go back and look again

Looks like struck thru maybe??? The M of UNUM looks all distorted???

Thank you Jim! I'm sorry I haven't dug this one back out yet but you are so good at seeing stuff, even on bad dark photos! Now you have me curious so I'm going to go find this coin in the pile!

Added: Jim, looks like a PSD hit with some metal at the bottom of the S where the hit terminates. I'm sorry my first photo was not very clear. Thank you very much for noticing this! I am still trying to get better photos and sometimes I get in a hurry and really mess them up!

Thanks for the follow up Vivien... Your pics are fine... On the full rev pic you have the M of UNUM looks distorted but on your close ups it looks flattened a little??? Is that the same coin??? If it is then maybe there is something up with your camera??? On your full rev pic it looks like you could have a struck thru on the memorial and across USA as well as EPU???

Thank you Jim for taking another look! Yes, it is the same coin. This is a good example of how bad lighting distorts things! My scope takes better close ups than it does distance shots, part of the reason is the lighting is harder to get right on full coin shots. Also... I tend to spend more time on the full shots of the side of the coin that has the thing on it that I'm trying to show and then I get sloppy with the other side of the coin.

Lighting can really mess with the pics... Thanks for the follow up Vivien!!!
