these clipped coins

Howdy, good evening, everyone.

I've come to see that with many minting coin errors, there are people who try to replicate the error themselves w/ anything from chemicals to some types of machinery...I imagine clipped coins are no different.

And, so, I pulled these coins from a big, assorted lot and am wondering if they look like they were clipped naturally/thru the minting process or if maybe someone did this on their own. I photographed the three pennies, two nickels, and two dimes from the obverse and the reverse, I know the lighting's not great, I usually take the photos outside w/ less reflection, but it's dark out now, so...for what it's worth.

Thanks,

Lou

Just ask yourself how do you get a square clip from a round punch press

 

It's possible. It's called a straight clip. Remember the punch is punching out blanks. When a sheet of metal is moving along for the blanks to be punched out sometimes they get jammed so in actuality the next blanks to be punched out are areas that are already clipped or the edge or the end of the sheet (that's where the straight clip happens)

 

Easy, end of strip

 

One punched slightly off of the strip.

 

Hi Lou, welcome to Cointalk.
Most of your coins look like manmade clips. Maybe 1 or 2 look like true clipped planchets.

 

I'm not too sure that all of them are genuine clips.

Real clips have a way of revealing themselves. First, the curve (if present - straight clips are also possible) will match the radius of the coin. The clip is created by the same punch that creates the planchet, so it has to have the same curve. Second, there's a feature called the Blakesley Effect caused by striking a clipped coin - the details opposite the clip will be very weak or not present at all. It happens in virtually every case, and the absence of it is a big red flag if the clip is of any size at all. Another thing is the way the rim and any adjacent details will blend into the clipped area - they won't look "cut off."

With those facts in mind, I think both the Cents and Dimes were done with tools post-Mint. The Nickels, though, are interesting. The 1962 looks odd on the obverse and appropriate on the reverse, and the clip is small enough to be variable on Blakesley Effect. I don't see a smooth curve, but I do see the rims blending in correctly (not likely to happen if someone mechanically clips it). Not sure on this one. The other sure looks like a legitimate triple clip, though, and a pretty interesting (but not unknown) coin. Let's await further opinion.

Not seein' much 'Blakesley', but that don't always happen. Shots of the rim (where the break occured) would be helpful.

 

Them Australians screw everything up!!

 

Yeah, but unlike most of the world, they like us.......

 

Also.. you should of asked this question under the Error Coins Forum

A straight clip occurs when the blank is cut from the end of the roll of metal.

For now - we still got over another year to piss them off!

 

Just a few from my collection

 

Nice!
