I think sometimes counting machine create wear on that area of the coins near the rim and runs around the coin. Just what coins go through.
On a collar clash the whole coin is not affected, thus the area where the die touched the collar, that will be affected.
Most of the time this is on either on inside rim or on the outside edge of the die, affecting the inside edge of the rim.
Note on this one from Mike mentions the hammer die is the one that is most often affected. (Some dies in the past had the obverse on the hammer die, but today some rotated this to the reverse as the hammer die)
Seeing the dime die affected on the outside edge of the die, of the upper part of the was hit on the face, it would make these collar clash line appear on the inside of the collar. It the gutter area was affected, it would affect the outer side of the coin.
Note the rim marked with the red arrow. This is what shapes the rim. The collar and the die working together during the strike. Adding the outside edge of the coin wither flat or with reeds. The reeds can affect the top of the die, making the marks on the inside edge of the die only on a small area of the die. Or if there is a slight clash, then the outer edge of the gutter, or the bottom part of the die can be affected on the outside of the rim, again only on a small area of the die that is slightly out of alignment.
(A new thought that hit me posting this comment) You figure out something new every day when you think on it a bit.

Why do collar clashes on affect a small area on the coin? Why are the affected areas in the side part of the rim and sometimes on the out edge of the rim in just a small area? What is a rim gutter? (New thought to me today.)
