...to which I still would like an answer.

 

Yeah I don't think no body has told you really what it is I'm sure their some body will Tell you something.Were is Paddy man at or collected nut they should no what it is you took a good picture of it.

 

This is the best information I could find.

The start of the Industrial Age (late 18th - early 19th century) brought a plethora of various minting machinery which culminated when around 1830 Diedrich Uhlhorn, a German mechanic invented the coin press which bears his name. The "Uhlhorn Presse" or "toggle press" substitutes the pressure from the screw of the screw press by pressure exerted by a lever and is now exhibited at a museum. Later on, the Thonnelier press, set up in Paris in 1845, was swiftly driven by steam then by electricity. The principle of the "toggle press" which allows several hundred circulation coins to be produced per minute lives on in today's modern mechanical mint, although the pace of modern presses nowadays is extremely quick.

 

Here is a good read from Esylum
https://www.coinbooks.org/esylum_v07n40a03.html on the Uhlhorn Presse.

 

Roger's book, From Mine To Mint, describes all of the machinery that was used from the mid-1830's to the 1930's, but the coin posted by the OP was dated 1827. Granted, I'm sure there was some sort of cutting tool or machine used to cut out the blanks, but I have to wonder if it was automated, cutting multiple blanks at the same time.

 

I found this on-line but it doesn't go into any more detail of where the blanks were ordered from
The War of 1812 played a major role in the absence of a Large Cent edition from 1815, as a wartime embargo prevented blank copper planchets from being shipped to the US. Though the Mint worked with the supply of planchets it already had on-hand, they had run completely out by the time it came to produce the 1815 edition. Fortunately, the war with Great Britain was put to a halt in 1816, at which point the US Mint immediately ordered more copper blanks to be used to create Large Cents.

 

It looks like a clean cut though. It just may be a clip.

 

I hope so...

 

Just saw this nice one auction is still going wish I had the money to bid for it.

 

Wow, thanks, you can see the Blakesley effect on the reverse. I gave mine a water bath and toothbrushing and am treating with VerdiCare.

 

Good evening all...Me too I want one please

 

I gotta find one for me.

 

As I said, I was just crusin' on Ebay, noticed this and thought I would take a chance.

 

Not sure my bath and VerdiCare did much good, but these are my pictures.
