The diameter of a LMC, I think, is 19 mm. The diameter of this coin at the feature is 19.2 mm and 90 degrees from the feature is 19.1 mm (see photo). Could this be a Collar Scar? Thanks for any help on this.

Looks like it was flattened somehow. Can we see the effected edge?

This is the best I can do for an edge shot. It has been flattened on the Obverse - is that impossible if it were a collar scar? In this photo, the Obverse is on the left.

Agree, seeing the edge would be helpful. So far I agree it appears to be probable damage.

I see some similarity of the "shaved" area on the obverse of my coin with that on an "Elliptical Strike Clip". I wonder if it could be related?

Do to the weakness and flattening of the rim in that area, I am going to say PSD.
Rest in Peace

My first thought was it got caught in a machine and was stuck there for some time....

I don't think I've seen a mint error that looks like that.

Don't know how that could happen at the mint.

I am thinking that it has similarities to these:

For the Obverse:

Is is possible to have a collar scar error without the coin being struck off-center?

It's a puzzler.

I see similarities between your coin and the ones in the links -- but it's still pretty easy to see how this could be simple damage.

If you think otherwise, set it aside. There's no harm in keeping one more coin.

The thing I am seeing pertaining to the collar scar is the examples in the link never encroached on the design elements where this seems to be happening with your coin.
An elliptical strike coin sounds like it would be under weight. If you coin is the proper weight I would lean towards PSD.

Thanks, all, for thinking about this. It will be a few days before I will be able to weigh the coin! All my kids and grandkids (and their friends!) are visiting for the holidays. I had to make room for them, so my coins and paraphernalia have all gone in the closet.

I am also looking at another possibility for this: A Type I Stutter Strike. The reference I am using can be found here:

http://www.error-ref.com/?s=stutter+strike

To quote from this reference:

Quote:
In a Type I stutter strike resistance is provided at one pole by a stiff but still somewhat mobile collar. It's surmised that the die, die assembly, or collar has to be loose as well because stiff collar errors are common but stutter strikes are not. After the collar gives way, the hammer die completes its descent in a position slightly medial to the original point of contact. The thin outlying crescent will be abruptly demarcated from the adjacent complete design. The die-struck crescent will, at best, contain the tips of peripheral letters.


The primary portion of this quote which interests me is:

Quote:
The thin outlying crescent will be abruptly demarcated from the adjacent complete design.


This may describe what is going on with my coin - and at this point I am thinking that it does describe my coin. Also, in their example - a 1998 Quarter - the area on the obverse under the date is flattened, it appears, quite similar to my coin near LIBERTY.

Now, my coin does not have the "die struck crescent" containing the tips of the peripheral letters. However, according to this reference, that is not necessary or required in order to be a Type I Stutter Strike - it is only referred to as the best example of this kind of event (if I am understanding their discussion correctly).

This is making more sense to me than a Collar Scar or some portion of an Elliptical Strike.

I have finally been able to weigh this coin - 2.47 g. I really don't think that is terribly relevant anymore, since there is only the vaguest similarity to an "elliptical strike clip". I don't think that is what it is.

I am still focusing on it being a Type I Stutter Strike as seen here:
http://www.error-ref.com/?s=stutter+strike

See my reasons for thinking that in my post above.

Pete2226, see your points, but sadly not on this coin. I was hoping some experts would confirm your findings to prove me wrong or to set it straight.

Yours has full rims and not showing any misalignments associated with the collar scar. The indentation seems identical to another coins rim getting pressed against and through this coins rim.

The only thing that kept me from saying so in the past is the fact the plating in the effected area is pretty much intact.

I would think that kind of damage would have left more markings to prove my point, but not there on that side anyway.

To some it up seems two coins pressed together to shim something up could reproduce this effect. Hope I'm wrong, Thanks, Doug.

Thanks, Doug. I am agreeing that it is not a collar scar. That was what I initially thought - but if you look at my last 2 posts, you will see that a think it is a Type I Stutter Strike - you can read my reasons why I think that above.

I don't think that I can change my title line to indicate that because of the time elapsed since my original post, but I will try.
