1996 LMC Die Cracks Don't Always Stop At The Rim!

A collar crack would only be seen on the edge of the coin.


As I understand it, the die has a shoulder on it which forms the inner side of the rim and the top of the rim. The collar forms the outside or edge of the rim/coin. So, if the crack is deep enough into the die, then it will involve the shoulder, too. So the crack on the coin will go into the rim. If you Google "coining die" many images can be seen. Here is one (clearly showing the shoulder on the die):

Thanks! I appreciate that you see what I am trying to say. To me, it looks obvious. Perhaps I am not remembering correctly, but I am thinking that there has always been the notion that a crack has to stop at the rim?

Very good stuff Pete! Thank you. I didn't know that about the die forming the inner and top areas of the rim. I had assumed the collar did it all. This will help me figure lots of things having to do with edges of coins. I basically know what I read on this site. That will help me tremendously. I suppose your coin's die had a deep crack. I, like most on here, have a fine mind, just need some education to go with it. Thanks again. EdUcAtIoN iS kEy!

Die cracks very frequently extend across the rim, it is nothing unusual. Since the rim is one of the last things to strike up though the crack will often be much weaker where it crosses the rim. And since the crack will be the highest point on the rim, on circulated coins the crack may be worn off on the rim.

I would think that the dies that doesn't have the ring on the outside of the die,

(Like the quarter in the image above) could have a crack over the rim. The rims on these coins and proof coins have squared rims. But some dies don't have that ring on the outside edge of the die. How do I know? When you see double struck coins, you don't see that ring line:


I notice there is a line from the obverse die, but the reverse die doesn't show this ring. Most coins I've noticed the die crack ends at the rim line (the edge of the die). So maybe the Hammer or anvil dies may have these on just on side of them and the opposite ones may not? So not all show the cracks over the rim. The dies maybe setup differently?

On the reverse of the nickel It doesn't show the outside ring of the die. So it may not have one on this die. Thus when it cracks, it would stop before the ring?

One explanation for this would be a shallow crack.

It seems to me that any coin with a raised rim will have been from a die with a shoulder to form the inside of that rim.
