1864 New Brunswick One Cent ...with A Planchet Flaw

Looks like a lamination error to me and would have fallen off at some point after the strike.

Cheers, Bill.

It was caused by an impurity (or gas)in the ingot itself. When the ingots (or rods or bars or whatever they were using then) were incrementally rolled to make sheets of the proper thickness, this small section was not fully connected to the rest of the surrounding metal. When the sheets advanced in the process for then punching out the planchets from the sheets, this planchet was cut out of a sheet already missing the thin piece, or it was just loosely attached. If it was still attached when it went to the striking process, it flaked off and ended up as a glob on another coin. However the planchet may not have had the thin piece to begin with. Yes, it's called a lamination error, but it should be called a "delamination" error.

Thanks for these explanations..(ie: delamination error etc..)

What attracted me more was the remaining detail of the Queens face (and other fine details) still very well impressed into the void.

I had trouble getting my head around how that could happen....and needed your help in better understanding this "kind of rare phenomena.".
