The reeding looks normal. I would have expected a "scalloped" appearance. Perhaps the edge was protected by a layer of wax. Despite the...
Unfortunately, the thinned portion of the coin with blurred details is a case of chemical erosion. The coin was probably suspended over a...
I've seen similar counterfeit second strikes in all denominations from cent to dollar.
Stained on the reverse, roller lines (roller stains) on the obverse. The latter is an error that traces back to the rolling mill. Value is...
Struck with a fake die on the obverse. The incomplete second strike and the soft, blended overlap between primary (genuine) and secondary (fake)...
This is a "rippled" coin -- an alteration. Most often seen on cents, the ripples are generally attributed to a rotating polishing or buffing...
Since the blurriness is uniform, the entire surface is affected, and there appear to be subtle "creases" to the right of Lincoln's face, it was...
No real mystery as to why a coin becomes an edge strike instead of a foldover strike. If the disc deviates even slightly from a perfectly...

As others have indicated, the strike wasn't strong enough to completely obliterate the original beveled junction between the planchet's proto-rim...
My article is now available in the online edition of Coin World (print edition to be mailed in a few days).
While I cannot be absolutely certain, the preponderance of the evidence now leans toward a tandem strike clip. Write-up is in progress.
I can send you a scan of the article(s) after it comes out.
I can promise you articles on both.
I now have Wes' double-clipped planchet. I am now less certain that these are strike clips. There's no suggestion of a saddle or any typical...
This might be a collar scar. I'll know more when I examine the specimen.
Your nickel has a cud (corner die break) on the obverse. It's not clear to me why the edge might have been vulnerable to damage here, as the...
These vertical striations don't really qualify as false reeding. These may have been generated as the coin was being ejected from a poorly...
I suspect that the reeding on the inside of the clipped edge is the result of a strike clip. Your blank was inserted off-center beneath a newly...
