Yeah, it doesn't look at all right. The rims and date don't fade out over the edge, but end abruptly, like they were cut. And there is no sign of the Blakesly effect opposite the missing area. Makes me pretty sure it is not a real incomplete planchet error.

This is an authentic curved clip. You can see metal flow in the date. The finned rim is also a good indicator. With a clip this large there is no Blakesley effect. Instead, with dies' impact confined to a relatively small area, the effective striking pressure rises high enough to generate a full design rim, with a little extra to spare.

Clips are usually more uniform in the curve are they not? It seems to have flat spots in the clip like it's not fully round.
It's a neat looking coin though.

Mike's attribution clinches it--he knows what he's talking about.
I would guess the non-uniform curve is also due to metal flow from strike pressure.
If someone were to fake this error, they would probably cut a perfect arc in the coin.

I would not have known this isn't a fake. Thanks for the info.

I would have thought it was a fake as well. First thought that came to my mind was ' band saw ' or ' jewelers cope '. See, That's why I love this site and it's posters.  |

This is why I don't support the use of the Blakesley effect as the sole determination for genuine clips. I always check for metal flow on the inside of the clip.

DVCollector,
"If someone were to fake this error, they would probably cut a perfect arc in the coin."
I had precisely the same thought.

I would like to pile on: Thanks Mike! My first thought was it was fake. Not only did you state it is not but why it is not. Added a little something to my knowledge so thanks also goes to rupester.  EDIT: I just noticed the title "NO DATE "D" Lincoln Cent incomplete Planchet ERROR" but there is definitely a D on it... Edited by CoinsKelly

What everyone needs to be aware of is that no single diagnostic is universally present in all curved clips. There are four basic diagnostics to look for. The presence of just one is usually sufficient to establish authenticity. The basic diagnostics are 1) Blakeseley effect; 3) fadeout and taper of the design rim as it approaches the clip; 3) metal flow in design elements bordering the clip; and 4) cut-and-tear texture along the edge of the clip. But as we've seen, other diagnostics are available like finning in large clips and distortion of the original smooth curve (especially when broadstruck).
