1 Cent collar slip or luck token

I got this cent recently in a paper envelope that said "odd stike through perfect" and
"obverse circumference greater than reverse" then "struck without collar, UNC.
And someone wrote "or came out of encased cent disc ?" What do you think?

Looks like it was encased in the past. They use high pressure to enclose Cents that causes this.

 

My thought is that if it was encased it would have some wear on it. It still has 95
% + luster, uncirculated condition, no scratches or marks.

 

It could have been encased as soon as it was minted then kept somewhere safe for a long time until someone decided to release it. I have done it.

 

Looks like it came from a lucky holder to me. Cool looking coin.

 

It was encased. It might have then been put in a drawer to sit for many years.

 

A Coin Bezel can alter the edge also
(Not my coin)

 

Doesn't an encased coin get smaller not larger? The obverse of this cent measures at 20mm. The reverse is 19mm.

 

It didn't come from the Mint looking like that.

 

Look at my post #7
I also mention a Bezeled coin.. different type of encasement. A coin can be altered many ways. Smaller or larger. I have seen many over the years.
I have never seen a Partial collar error slope the way yours does. Only encased coins. Not an error.

 

I agree that it isn't an error. The finning on the reverse rim and the tapered edge indicates pmd. The missing pieces of letters is kinda cool and I suspect may have been the reason for it being saved.

 

I can not understand how any type of encasement could make a coin larger. Please explain this.

 

They are pressed into the holder. The rims and edges change based on the type of holder being used and how it's being pressed.

 

I can't give you an exact correct explanation but copper is a metal that can be expanded if enough slight pressure is administered to it.

 

Just like a coin on train tracks
Under extreme pressure metal expands

 

Presure from the inside to the outside will make metal larger. Is not that why collars are used in the die stamping process to retain the corect size of a coin? If you apply
presure to the outside rim or edge of it will not squeeze it a make it smaller or even buckle and bend with enough presure?

 

Struck without collar - If this was the case then the entire circumference would be expanded, Obverse and Reverse and that is what is called a Broadstrike.

 

Yes. But Bezels and Encasements were made in many different ways. Some did not surround the Cent all the way around. Some sloped strangely. Like I mentioned. I never saw a partial collar strike with a slope such as your Cent in question.

 

In trying to explain why I believe it's post mint, if the finning on the reverse rim were true to the original strike, it would indicate the collar was engaged when the coin was struck. If it were only partially engaged there should be a clear line around the rim where the collar stopped and with the lack of lateral resistance, there shouldn't be any finning.

 

Put a pat of butter on a plate. Now press the butter down. It's still the same pat of butter but it's now thinner and wider. The same thing happened with your penny, except, with your penny, only the edges were compressed, making them spread outward, moving in the path of least resistance.
