Okay, I'll wait. La-la-la-la-la, ho-hum. I can't hold my breath much longer.

 

Some folks call it doubling. Lol

 

I've seen that.

 

No idea. I can't recall ever having seen that shadow effect. But then I've not been collecting but 5 years.

 

Shade. Lack of sunlight

 

Halo.

 

I actually know this one!

 

Totally clueless as to what the answer is.

 

You mustn't be a Morgan guy....and that's fine. I don't think you see it much on other series..

 

Indeed, you are quite correct.

 

I believe it's called Pull Away. Something to do with what happens to the metal as it is pushed and stretched when the coin is stuck. Causes the metal to not tone at the same rate as the surrounding metal.

 

This "effect" is commonly seen on originally toned dollars. BurrosCoins, posted the answer: "Pull Away."

It is a good bet that most of the long-time members here already knew the answer.

A "halo" would completely encircle the numerals.

 

Just lucky. I usually don’t get these right. Just happened to come across one that was similar a while back. Still learning.

Thanks for the quiz @Insider

 

When I first encountered Pull Away on a Morgan I thought the coin was counterfeit.

 

It can happen on any coin that has sharply defined stuff near the rim. You usually only see it on uncirculated coins, which is why you tend to see it on Morgan dollars. This 1697 sixpence shows it on a few of the letters. III DEI on the obverse and REX 16 on the reverse are most obvious.

 

What causes that Messy?
Is that an out of tolerance planchet?

 

Metal flows from the center outward when the coin is struck. The peripheral lettering interrupts the flow a bit. As a result, the fields just beyond it have less flow and end up toning differently. The presence of a collar die seems to make it more pronounced. I can't explain beyond that. Guessing that more flow means a more "raw" surface for toning, while less means that whatever was on the surface at time of striking is now more embedded in the metal, making it resistant to toning. Planchet preparation would also come into play, then. A bright, scrubbed planchet immediately struck might tone without developing pull-away toning.

 

Thanks @Insider this is fun stuff. In the crazy kinda of way. I learn something.
