I think Halo is onto something there - but just how thin is it?

Not sure exactly what Halo is suggesting, but Dearborn I think I mentioned the weight in the title and twice in the description. I could put a micrometer on it but I think that being roughly 22% of the weight of a normal coin one can get the idea this thing is very thin.

Fantastic looking error! Great find.

My thought was it split after strike. Not seeing the "Struck Through Unstruck Planchet". Thanks, Doug.

Halo, if it were just a split planchet after the strike, then there would be a ragged look to the surface. They don't split clean like this. The reason for the smooth surface is from the unstruck planchet it was struck through.

I hate to bother Mike all the time, but maybe his input would be most useful. John1  |

I absolutely agree with TB. The obv appearance has all the earmarks of a struck through.
A split after the strike produces a completely different surface (where the two halves were joined), compared to this one.
A split after the strike would produce a "linear" looking uneven surface similar to "laminations" that have separated.
Words of encouragement are one of the major food groups.
We need to consume them regularly to thrive and grow.

Tropicalbats is correct in his diagnosis. This is almost certainly a split-before-strike planchet that was struck against an overlying cent planchet. The finned reverse rim is a consequence of the increased effective striking pressure. The only other possibility is a planchet derived from rolled-thin cent stock. But very few examples are this light. I've only seen two in this weight range.

I am late on this topic.
1. Could be a very thinny planchet before 1980.
2. Could be split on the blanking procedures (I saw some totally split planchets on this step.
3. Another thing I saw was the planchet was split during the milling.
For me the No 2 and 3 are more realistic. No 1 is know happened but it is a mistery how could happened because the rolling are cut on the ends, and on the middle of rolling you can not have this differential. I saw this kind of verry thinny planchet on old Silver Dimes not on modern cents. Mike saw much more.
Other topic here was after strike. The answer is clear NO. If was after strike or in the process of striking, the surface will show the molecular pattern.
For me the big mistery it is: I see rims, so this blank pass the milling without deform and after glue to an normal planchet during the annealing and then dettachet due to the strikes forces. This it is the Mistery. Other option it is was an man made error, but one of the most inventive ever see.

Thanks, TB, Mike, Pete, Silvio and others.
My minds eye was drown to ragged rims edge where should be flatten a bit more and the ragged look seen on some of the interior high points. If struck through, I'd thought it would be a bit cleaner or smoother in those ares.
Also thought it was a flawed planchet going in for sure. Maybe a nearly separated clam shell. Thanks, Doug.

Thanks everyone for an excellent discussion of a nifty coin. Special thanks to Mike for such a clear analysis.
