Error Coins

Could someone explain the difference between a coin struck: Broadstruck vs Broadstruck out of Collar?

Also, when PCGS slabs a coin Genuine Wheelmark (Obverse or Reverse), what marks should be looked for?

Explanation with photos would be appreciated.

Last one, what defines a "Chainstrike"? I am asking this one because I have two coins, the first one is labeled "Struck 80% Off - Center & Chainstrike", and the second one is labeled "Struck 95% Off - Center" only.

Thanks,
Tim

Broadstruck coins by definition are struck “out of the collar”. They are the same.

A counting wheel mark will be a shiny area that disturbs the luster in a design struck area and looks like a smudge of sorts.

“Chain struck” means the coin was up against another off center planchet when it was in the press getting struck, causing a flat edge where the two planchets meet. Sometimes both coins are present and they make a chain struck “mated pair”.

Wheel marks can be difficult to locate and see, in-hand and often, impossible to see in images.

On the wheel mark, I have thought this ngc short article does a good job at explaining / showing it.

Thank you all for the comments! I just didn't know what I was to be looking for on the wheel marks, the NGC article explained it. I'm still confused with the two True View photos as to why one is marked "Chainstrike", and the other is not.

Sorry for elementary questions, I'm just a believer in the thought process that the only stupid question is the question not asked. . .

I am not an error type, so this is just my reading of information.

The CONECA has a brief definition of chain strike:
When two planchets are struck while resting side by side, the result is two off-center coins, each with a flattened edge.

So from that it is defined by the edge due to the two planchets resting against each other.

error-ref.com gives some examples at:

So in the first one labeled with the chain strike, it appears the edge is more straight. This being caused by the chain strike.

If more interested in, then the above are in the Resources thread pinned to the top of the US forum or link below. The various links are in the OP (or first post) on page 1 of the Resources thread.

Based on what was posted before, the edge of the design portion would be flat due to it being up against another planchet when struck.

I assume the top photo is the chain strike?
