NEAT QUESTION HERE

[parasite]

What causes the reeding on some coins to be missing? The one I found has not been worn, buffed, filed or sanded off. It appears and disappears around the circumference of the coin at different locations. Where it does appear, it is very weak looking.

It was probably reeded improperly.

What are some causes of this happening? Are there more than one?

The coin could have moved while it was being reeded. I don't know if there are any more like this. You will have to do some research to find out.

Exactly what I am doing . Thanks for the responce.

There are probably several reasons for this Pat, but the ones that come to my mind are (1) improperly adjusted collar (the edge die where reeding is imparted these days) or (2) a broken collar, but likely (1) since you say some reeding is visible and the coin is apparently not broadstruck (struck without or outside a collar).

On USA coins made since the 1830s, the reeding is applied by a die collar at the moment of striking. Some collars have shallow reeding, as made. Others become worn with repeated usage. Finally, the way the obverse and reverse dies are basined (given their radius or field curvature) affects the flow of metal and the filling of all dies, including the collar. Some coins are frequently seen with shallow or indistinct reeding from this last cause, 1921 Morgan Dollars being a good example.

Thanks for the responces. It sounds like the metal flows into all the voids when it is struck from the extreme pressure and heat that is generated. I guess if the collar is worn or not in position then the metal won't be squeezed into somthing that is not there.
