These are the only images in two different orientations: The reverse is perfect. The edge is perfect except where it is affected in the image. It appears that something hit this coin while still in the die chamber. The reverse and reeding is perfect. This mark looks like another coin's reeds were struck into it while still in the die chamber. There is no evidence of PMD so I would appreciate
Quite likely as you surmise, a detached rim burr from the previous coin was stuck in the chamber. Result was a strike through rim burr.
Could it be that somebody bit the gold coin? Biting gold coins to test their authenticity has been a common practice for a long time. However, the reasoning behind this tradition has changed over time. Why Do People Bite Gold Coins to Test Them? (moderncoinmart.com)
Well, I have seen damage like that on this nickel and SBA $1 caused by the crimper that seals the Mint cello... And I have seen some on only one side before still in the original Mint packaging, but I don't know if gold eagles were ever sealed in them. It could also be a fragment with a reeded edge from a different coin that got rammed into it.
Thanks Joe. Now we are all going to get together and learn something. I'll post the edge and reverse of the coin (later) because we'll need to see it to figure out what happened. I don't know for sure. We have two choices...crimp damage (after struck) or struck thru burr while still in die chamber. Since the edge and reverse are undamaged, I was leaning towards strike thru BUT IT LOOKS JUST LIKE CRIMP DAMAGE! Anyone know if these were ever packaged privately or at Mint.
Very ambiguous question with out both sides of the coin place in question. By what I see it is perfect marks of other coin hit. Some one say before Rim Burr???? just there??? To see the two face of the coins and then take a conclusion. Till that moment for me an clear PMD.
