Ok , here's my Two Cents worth. I don't think it's a struck through. Anything sturdy enough to make that much of an indent on thr reverse would have created excess pressure to fully strike the obverse. The collar obviously deployed durring the strike or this coin would be broadstruck to some degree, yet , the anomaly freely extends through the rim which should have blocked the collars deployment . Were this a struck through the details close to the anomaly should be well struck but there is, to one degree or another weakness of design adjacent to it. What this appears to be is a Rolling Indentation. Something found it's way into the rolling mill and was rolled into the coin metal before the blanks were cut. This mark was there before the strike. The full weight of the coin could be from the metal being rolled thick. My Two Cents worth |

So it's a Rolling Indentation? Does this happen rarely? Thank you for the new information. Coop will probably elaborate eventually on what you said. Thank you for your help.   Errers and Varietys.

Willburton, thank you for the link. The title says it is Struck Through Rim Burr.

David, the one on ebay is a struck thru, note the rim has formed, a in collar strike. Your coin as Stoneman indicated is also an in collar strike for the rim to not Broadstrike. had to be a planchet flaw, pre strike boo-boo that would account for the dimpling obverse as the metal was moving around. Where in the process, rolled stock, cut blank or upsetting process not sure. Could have been a toothpick on top of the stock plate as blanks were punched? THAT would explain the distortion on the Memorial, points of roof don't line up. AND it will explain the weakness seen on either side of the chasm if it were a planchet flaw, that would be caved in around it on the planchet. This event would have occurred during the rim upsetting process when the planchet was squeezed together to form the basic rim form. Note the D of United just falls away, strike thrus don't do that.

Crazyb0, I am scratching my head on this one. I'm not exactly sure what to label it as. Would Mike Diamond know the answer? Errers and Varietys.

A normal strike. The collar has "deployed" meaning has risen to surround the planchet placed on the anvil die. The hammer die then comes down striking the coin forcing the metal into the designs on the dies and expanding to the limit of the collar which then forms the rim. A "partial collar" or "out of collar" means something has stopped the collar from coming all the way up (it goes down when coin is ejected). This forms the brockages where the coin spreads out or the planchet moves off the reverse die and an off-set strike occurs. Or like your "Railroad" rim doesn't come all the way up so the rim is only partially formed and the rest "spills over". On reeded edge coins, only some of the reeding is formed.

I read the article that was linked to and I think I found a problem. On that page it stated the coin will be underweight,Were E&V said the coin was normal weight. Can that type of error occur and the coin remain at normal weight?

Newbie, that was in my mind too. I have weighted it multiple times and it weights the normal amount (3.1 Grams).

That's why I said it was my Two Cents worth. Where the anomaly crosses the rim eliminates two things, a strike through for the above reasons and post strike damage because of no swelling of the rim. This anomaly was in place pre-srike. The rolli g mill is the only step that would impress a shape into this surfce of the eventual coin before the strike. Were the foreign object hard enough it possibly could have spred the rollers enough to add wieght to the sheet metal this blank was cut from. Enough to balance the loss of metal from the imprint. Do I know this happened, no , though the anove evidence points to it. Thus My Two Cent worth |
