Partial Collar Strike per Alan Herbert's Book... Flanged Partial Collar Strike:A coin struck with the obverse die as the hammer die, the collar only partially raised around the coin, showing on the struck coin as a flange of the coin metal which spread out above the top of the collar, parallel to the upper (obverse) face of the coin and extending beyond the normal diameter of the coin.Tilted Partial Collar Strike:A coin struck wih the collar in a tilted position, showing on the struck coin as a flange of unequal thickness that tapers in both directions diagonally across the edge of the coin and may show only on part of the edge.I submitted this Peace Dollar to NGC to be graded as a "MINT ERROR" and NGC claimed "TOO MINOR, NOT RECOGNIZED" What do you think? 1923s_pc_o.jpg1923s_pc_r.jpg

I have to agree with NGC on this one. This coin would pass "quality control" at the mint as fitting within strike tolerances.

 

This is kind of why the 1955 DDO cent is not a "mint error". The mint was actually aware of the problem at the time, but decided it was acceptable quality, and were released as acceptable coins.

 

To be a "mint error", it should be something the mint would reject as not meeting standards.

Please note the obverse die as the hammer die with the CCW rotated doubling. Also the rim from k-10:00 to k-1:00 is flanged as shown in the image.

 

Tilted Partial Collar Strike...

Is a coin struck with the collar in a tilted position, showing on the struck coin as a flange of unequal thickness that tapers in both directions diagonally across the edge of the coin and may show only on part of the edge.

 

SIZE DOESN'T MATTER IN WHAT A ERROR COIN IS...

Hobo - NGC is correct on this one. What you have there does not appear to be a partial collar strike, and it isn't a tilted partial collar. And you certainly can't tell this from just looking at the obverse and reverse - a picture of the edge is required to make this assessment.

 

I'm not entirely sure you understand what this error means. When the coin is struck, there is actually a third die - the collar, which contains the coin and gives it the reeding. If the planchet is not set properly in the striking chamber, for example if it only goes halfway in, only half of the edge will receive the reeding. The other half will have a plain edge, and the plain side will appear noticeably larger in diameter than the other coin. This is why the Morgan in your second picture appears distorted and irregular around the edges.

 

A tilted partial collar occurs when the coin is in the striking chamber crooked - the reeding is not even around the coin. At one side, the reeding is only on a narrow bit of the coin, on the other side, it is much thicker. But there is still the distortion from the uncontained half of the coin. A tilted partial collar is really just a variety of partial collar. There was actually a recent thread on here showing a great tilted partial collar. Maybe someone has the link?

 

This error does not usually have the appearance of your coin. You might have a misaligned die, or any number of other minor errors, which are too insignificant to list.
