Hello! It's been a while since I annoyed y'all, hasn't it? Today, I bring photos from my new high res 250x scope, showing my most recent find; a die cracked war nickel! 'What's so special about a die crack?' might be what your thinking right now, and my answer to you is the location! In this specific coin, you can see it runs from the top of the Monticello building, to the bottom of the top rung of the S mint mark, making it look like a $ sign! Can only be good luck, right?
because a straight line is the shortest distance between 2 curves. there is a reason why rivers run under a bridge. you take the high road and i will take the low road.... a got a million of them... an s upside down is just another s.
The Details in the Working Die are incuse, so that when the Planchet is struck the metal is forced into the recessed areas; if there is a Crack (or Die Chip or Broken Die) the metal will be forced into that area and if there is enough of a metal flow the resulting raised metal feature (i.e. Crack) may be higher in relief than the Mintmark, which is what I observe on the OP's Image.
It is too straight to be a crack. A crack doesn't "stop and go" when it reaches a device (letter). It continues in the die steel, so we should see it through the letter. It could be a gouge in the die, but it is not a crack.
The issue with what your saying is this is a very well recorded die crack. Here's another couple of examples. https://www.cointalk.com/threads/2-jefferson-nickel-die-cracks.88440/
Does it matter that the crack on this nickel is not in exactly the same place through the "S" as the one in the example? The one in the example is more to the right.
Well, there is 3 or 4 cracks like this for this year. There's also one that runs from the far right, bisecting the coin, that leads to a major die break. The ones I showed were what popped up first with a quick google search.
