wierd rim on dime

Red - is such an agressive color for an admin name on the right. Will have to post in support forum.

I found this link that I thought was cool - http://www.uscoinage.com/uscoinage/errors.html. The reason for the link is the blank planchet - the raised rim almost looks like it is beveled slightly. The rim on this dime looks more like the blank planchet rim - just saying that it may not be machined, but am not an expert.

 

along with what GDJMSP said, there is not any copper showing through. So it would seem like this happened before it got plated

 

plated?

 

Actually quite simple using hard rubber plugs - one in the headstock, one in the tailstock and the coin in between. Run them together with a lot of force, then take light cuts on the coin until you get the result you want. Another way, probably not done with this dime, is to epoxy the piece to the end of a rod chucked in the headstock, then take the light cuts to get what you want. Then dissolve the epoxy chemically.

 

I'm new at this. But isn't the nickel plated on the copper before it gets struck

 

I like this one. I want to know how this turns out.

Here's a point though that might be considered...if someone went through the effort to make a counterfeit dime, why would they make it so dissimilar to other dimes? I would think that this would be picked out in a snap.

 

It's not plated. The strip from which the planchet is stamped is three layers - a layer of copper between two layers of copper-nickel. This is rolled to the correct thickness and, in the process, is bonded together. Then the planchets are stamped out and then the coins are stamped.

 

Are the three layers the same thickness? I believe the copper-nickel layers are thinner, which would allow the copper to show through (as previously stated) if machined. Anyway, I don't think it was machined (in a lathe anyway)... there does not appear to be any circumferential tool marks.

 

You folks don't look at the edge of too many coins do you? This is a perfectly normal coin, just not well struck.

When the planchet comes from the upsetting mill it has a rounded edge. When it is struck in the press the planchet expands outward and the center of that rounded edge makes contact with the collar first and begins to create a flat edge. As the strike continues and the planchet continues to expand that flat edge gets broader and broader until on a full strike or a proof the edge meets the rim and you have a nice square edge. But if the coin is not fully struck you just have a flat spot on the edge (reeded in the case of dimes, quarters etc) and the start of the rim and a roughly 45 degree bevel from the flat spot on the edge to the rim and that bevel will be seen both above and below the flat edge. The stronger the strike the smaller the bevel.

 

So my dime is not fully struck

 

I have to disagree this is not no normal dime I look at my coins and examine them i never seen a dime like this only simular to a partial collar strike but I'm not even sure aboutthat anymore since i can't relly make out the rail road rim. This is not a normal dime and not well struck. I think you better take a closer look at the picture below and then make another judgement,

The half dozen, or so, pictures you have shown are all of the obverse side rim. Care to post a couple of the reverse side rim?

 

I can;t it's not my coin, I would like to see the reverse to try and come up with a soulution what this coin is. I save the obverse of the OP's pics. the only way he could give us pics of the reverse if he reads this post

here ya go.

 

Well since i have shots of the reverse I see a railroad rim an indication of a partial collar strike

but it's BEVELED.

 

It is not a railroad rim,
Can't remember where I borrowed this info, but here it is.
The error is commonly called the “railroad rim” even though it is the edge, not the rim, that is affected because it looks like a railroad car wheel. This coin exhibits a split-level edge where the obverse (hammer die strike) has expanded larger than the reverse (anvil die strike). This occurs when the collar jams on the shaft of the anvil die at a position where only part of the planchet is contained in the collar. Care should be taken not to confuse this error with a coin that has been damaged by being forced into a “lucky” coin holder. The partial collar strike has two distinct diameters.

 

That sounds just like my attempted art work. I cannot swear what it is, but it is not a "railroad rim".

 

I just got my first....talk about cool!
