Really cool! What causes this? Striking error? Why just the date and not the whole coin? Added value?
I Can't give you an exact how, be ready to show more photos to better exam the whole coin.
Merry Christmas !
Welcome to the forum!
A nice example of mechanical/machine doubling.
No added value.
It's mechanical doubling. Notice how the features are flat. That's due to a die that's loose during the strike, not a die that that received a shifted impression from the working hub.
Wexler has a good explanation on his site under the tab "Worthless Doubling"
machine/mechanical doubling, no added value
I greatly appreciate the responses! However, I still can't picture how it happens that just the date is misaligned and the rest of the features are not?
It's not misaligned. The die and/or planchet move slightly during the striking process. MD is rarely on every design feature (although it can be).
That's a wrap.
