Hammer strike?


I dont know what caused this but I would think if it was struck with a hammer/something - that both obverse and reverse would show damage.
Am I correct in my thinking ?

I was thinking of Indent struck.but the Rim looks alarming to me the way it is flattened and in One are is pulled outward.

Could it be an in-collar indent strike-thru error? I googled that, and some of the examples look very similar to this. I think it's possible, but I'm not 100% sure. The reverse looks pretty clean, if something hit this post-mint, I would think there would be more damage opposite the hit.

Correct, but it can be done with a vise, without damaging the other side by cushioning the opposite site with a piece of wood.

Not Post Mint Damage! It's a genuine error. It's a Partial Indent. If you look at my profile picture, that's a Partial Indent error on a 1981 Canadian cent that I found CRH from a circulated bankroll from a bank box. That's exactly what it would look like.

Hi all, if it was a hammer strike wouldn't the rim also be flat?

Cheers Gutshot

An indent strike happens when a plain planchet intrudes into the striking chamber and the coin(s) are struck together. The planchet blank image has been transferred as blank while all details of the hammer die strike would appear on both planchet and coin. Like to have the planchet too!

Another question to the class:
"Will this coin be under weight or over weight?"

Coop, it will most likely be underweight because of the indented planchet surface.

What was the weight when the planchet was made? Take away what was lost? So what would the weight be?

No one answered for a few hours.
But was anything actually removed from the planchet? Do coins with a mint mark, die crack, die chip, die break or Cud actually gain or loose weight?

The weight then must be the same since nothing is removed from the planchet nor is anything added to it. Weight must be the 3.1g that is normal for a copper planchet.

Correct. The metal is just rearranged.
