This one was in a small lot of error coins I picked up. Just liked the overall high grade of the coin as I generally don't buy many 1999 or 2000 errors since those dates are common for such things. It would appear that given the bit of mayhem along the edge opposite the brockage that the coin was seated on maybe a bit of a partial collar. 1999 Lincoln Memorial cent mint error - broadstruck with partial brockage   |

Don't really understand this sort of thing, but most impressive.

Broadstruck would mean out of collar. So there was no collar present. Looks like the indent was on a previously struck coin. (thus the mirrored EPU devices on the obverse) Not sure what the correct terms would be exactly on this one. It would have been nice to see both coins that was affected?

Thanks! As for terminology, it is a partial brockage, not an indent as Coop suggests. An indent would have been if it were struck through a blank or unstruck planchet, which this clearly was not. I called it a broadstrike since all the devices are on the coin and it is larger than the size of the collar so it must have been struck out of the collar. This terminology matches what NGC puts on slabs for similarly struck coins, which may or may not be correct but it's what I've got to go on.

I don't understand how these are formed, but it is an impressive example for sure.

Think of it this way. A struck coin is sitting halfway in the chamber. If the machine is operated that will become a double struck coin with the second strike off center. But in this case a planchet was inserted over the coin that was about halfway in and then the machine operated. The obverse side was struck through the coin and part of the design from the intruder coin was put on the obverse of the new coin (called brockage) while the reverse was fully struck as there was nothing between it and the die. Somewhere out there is the other coin, which would have ended up still as a double struck coin just now it would be uniface.

Very nice error coin! But it raises a question in my mind. It shows that the partial brockage has spread and grown. Could the second coin be a die cap, or can a single strike stretch the second coin this much?   Congratulations on another wonderful error!

I have never fully understood how the lettering reacts to the deformity during an out of collar strike, but this looks pretty normal here.
