1937 P (?) Penny Struck Through A Die Cap On A Tapered Planchet?

Thanks Coop, so if I'm understanding correctly you believe it's one half of a split planchet after strike error?

That would certainly account for the missing weight.

Very nice find!

The striation lines would be from a rolled on scrap metal that was uneven in surface thickness. If the rolled on stock would be even thickness, it would not create the striation lines. It would be adhered to the stock hot rolled stock, but being cool, could fall of at anytime later after the strike.The thickness would have been on the 10:00 thickness of the edge of the coin. Thus when it came apart, it broke off that location of the planchet.

Similar to this coin, but attached on the outer edge instead of the center.

Like a loose clad. Note the edge of the coin?

Thanks for the lively debate. I always find conversations like this helpful for better understanding how errors like this can potentially occur. One thing I probably should have specified is in the original pictures I posted the coin in question is on the left when I was doing the rim comparisons. So the first rim picture is a comparison of the thick edge of the coin in question (left) to another Wheat penny (right). The second picture still has the coin in question on the left and it compares the thinner rim to another Wheat penny on the right.

Let me know if there are other pictures I can provide that would be helpful.

Thanks again!

Hey Everyone,
I wanted to post an update on this coin. I had heard ANACS was pretty good regarding error attribution so I gave them the coin to review. I noted that the coin was likely on a tapered planchet. The coin came back with the following attribution:

1937 1C Struck Through Late Stage Capped Die
AU 58

There was absolutely no mention of a tapered planchet or the low weight. In the same group of coins I sent off another one that had a straight clip on a tapered planchet and that one was attributed as a straight clip and instead of attributing it as a tapered planchet (which I've seen done on their labels) it simply listed the weight as 2.6 grams. I find it odd that the 1937 coin would be confirmed as struck through a die cap but have the 2.71g weight ignored.

If this is indeed a tapered planchet struck through a die cap those combination of events seem exceedingly rare and I'd love to get it attributed as such. Any recommendations? My next thought would be to send it to NGC but I'd hate to spend the money if it won't get attributed with both events.

Thanks!

Nice find.
(Missed another one the first time around.)

ANACS may have gotten it wrong on the label, especially if you put the wording in your description on their form.

I would contact them, explain the missing info from the label, and ask them to correct it. You might even provide the link to this thread where Mike confirms your initial attribution.

At the very least they should have included the weight on the label.


As to the discussion in the thread, IMHO, the reason the reverse rims struck up so nicely for a tapered planchet was simply that the die cap provided the additional volume of metal for the reverse rims and probably overlapped the obverse rim, flattening it out.

I called ANACS and they were incredibly nice and offered to take a 2nd look at the coins. Really superb customer service. I'll post an update with the final results.
