2005 P Awsoome Nickel Clash

On his cheek.

PMD.

I thought that mark on his cheek was the hair on the back of the Bison's rear leg. ?

You'll see often times on Lincoln Cents within the Memorial clash marks that represent 2 or 3 hits and can have a progressive look. I've seen on 2007 Jeffersons multiple clash witness marks observable on both sides of the coin, but so light that they don't merit saving (if you watch for the shiny marks on the 2007Ps, you'll see what I'm talking about). The marks on the cheek look like Reed Marks from a quarter or something, but a contact mark as opposed to a clash. Have a look at that coin of yours around Liberty; if shiny, widespread mark, it's probably a very light witness mark to a clash (spendable).

Good luck! You'll find one. Harder in nickels than cents, but more exciting when you find one.

Stop and think for a moment. On a die, the devices are negatives, so they can be positives on a coin. The highest point on a die, then is the lowest point on a coin - the fields. So when two dies come together, the first thing that contacts is what's at field level.

It's not the device that clashes, it's the outline of the device. The edge.

Now, it stands to reason that the devices, being low in the die, are not going to clash. They're protected by the higher surfaces of the fields. So, a clash which actually managed to put transfer into the devices of the other die is a strong clash indeed. Weird thing, though - if a clash that strong happens, sometimes you'll see them with clash artifacts only in the devices. They can successfully polish clash artifacts off of the fields, but you can't reach into the device with the polishing tools....

Another thing to think about is that device depth is deceptive. The less-pronounced parts of many devices are virtually field-level, and will receive clashing earlier than you might think. So when you see what you think might be clashing on a device, your first thoughts have to be about how deep that device is on the die and how easily it might receive a clash.

Well put Dave.

Well, Ken probably has stuff that's clashed so hard the features poke back out the reverse in the same place they normally belong. Which would make a liar out of me.
