crushed rim?

Dick · Expert Member

BJ, I have found several coins, (cents), that appear to have a "crushed rim" look to them. It affects both sides of the coin. It also appears to be only on one area, obv/rev, of the coin. Others seem to have the effect go all, or nearly all the way around. They have been cooked, so it will be a while before they arre available for photos. I'll keep you posted.

Steven, the rim "crush" I refer to is not "flattening", but a lateral action across the coin. BJ has knowledge of this, and is actively working on it, (and a thousand others,as well)!

Hi Dick- I have to see pictures of the coins in question before rendering any kind of opinion on them.

As BJ says,
Hard to tell without photos but it may be the workings of the demon encasers taking a coins and wrapping them in aluminium to advertize there goods or upcoming events. Those destroyers of coins for the sake of pride in there products. Then the child with a hunger for penny candy rips the encasement from its precious metal to allow for the barter.

Dick,

Sometimes a minor clip will look like a flattened rim on both sides of the coin in one area. If the clip was small then when the coin is struck it sometimes flattens it enough to hide the clip but leave the rim flat in that spot.

A clue that proves this is if the coin also has a minor flat on the rim on the opposing side. The reason for it is when they run the blank through the upset mill (rollers that create the rim on the blank before striking) the area with the clip makes it not tight in between the rollers on the area of the clip and also on the opposite side. There is a name for that effect (whats the name?) that graders use to verify a coin is a real clip.

Can you get a picture? Maybe your picture will show it.

Ed, and Steven, You get an "E" for effort, but, sorry, no banana, er, cigar! The effect I refer to is not an edge effect, as you believe. This ocurrs INSIDE the rim area. It has nothing to do with the upset mill. I am in the process of getting photos of several, for the beneifit of all concerned. If they come out today, I'll edit this post, and show them.

these are not the best, but maybe you can see the areas of compression. They are not the same coin. They are NOT gouges. BJ, opinion?

Dick i dont see much on your pic's but what i do see looks alot like rolling machine scratches.

Dick · Expert Member

Gary, do you refer to the ridge hust inside the rim? That is not a gouge, like the counting machines leave. It is a rounded ridge that is visible on both faces of the coin.I have to get my other setup mounted again so i can get larger views of smaller areas, again.

let me know when you find out Dick i have been putting them in the roll box to go back to the bank. if they are what i have been seeing here in Tuc

Dick · Expert Member

Gary, if you put up an image of one of yours, I can tell you if they are the same. My setup is pretty crude,and the images don't come out the way I want them. Mine are all "80's.

I see what you are talking about now. There has been discussion on this before but I can't remmember what was a cause for this. Possibly related to composition of the metal. I just can't seem to remmember.
I am sure that it was not found top be collectable an very common in th 80s. I will try to find a previous discussion or someone else may recall prior to that.
Steven

Didn't find much. Seems to be a mechanical issue related to the copper plating and the the zinc planchets. I would suppose technically a mint error but I would not believe there to be any value over face.
I'm sure there is someone here with the right answer that will come along soon.

Dick,

I think I know what you're talking about. Look at Bobs picture of one of the 84 DDOs I recently found. See the line going through the motto right through TRUST. Is that what you're seeing?

I was sad that this neat DDO had it but glad it didn't effect the doubled areas, it's not after mint damage but it's not collectable either. I wonder if there are examples of the same DDO without it????

I don't know exactly what it's caused by, maybe die wear or something but I only see it on zinc modern stuff mostly in the 80s maybe somebody can tell us.

Look at the pics of the 84, is it the same thing you see on TRUST?

Ed, that is EXACTLY what I have been trying to show!I also have a hand full of 1984, "P", and "D", that I'm trying to find the marks for the DDO. I pull all 1982's, and have been holding the '84's, for further checks.
