die clash?

[Tuffjump]

Lines running from OF east to the designers initials at the steps also running from the N in United to the building. And other lines above and between stated lines. Is it a die clash and if it is why it the reverse showing on the reverse?

These are die scrapes from a feeder finger.

interesting

I have never heard of that. How does it happen and does it have a premium or should it go back into circulation?

Ahhhh.....I think I see what you are saying. Would the lines be in relief or incuse? These lines are in relief looking very much like the building especially at the top of the coin ( as it sits in the pic) and also at the bottom. Scrapes would be incuse wouldn't they?

The scrapes are incuse on the die and raised on the coin. Presumably a mistimed or mis-positioned feeder finger or mistimed cam (on which the anvil die rests) would be to blame. There is a small premium attached to this form of die damage. Regardless, I would keep it as it not something found routinely.

Thanks Mike I just had a re-look at the coin and understand now. I thought I was seeing vertical marks between some of the lines making me think it was the building and they are not there making it all clear. It's appreciated.

another Q

I'm not really sure I understand how it happens. The lines are in the field but not at all on the building. If the die were scraped by the fingers wouldn't the entire side of the coin show the scrapes. As an example where the columns are there are no lines yet between the columns the lines are plainly visible. The lines seem to be under the designs.
Now to answer my own question......would it be that the scrapes on the die made by the fingers are only on the field because everything in relief on the coin is incuse on the die thus avoiding scrape marks? A case of thinking as I write. Do I grasp the concept or is there more to it?

[NearDateHound]

That's it exactly. On the die itself, the features which are raised on the final coin are recessed, so if something scrapes across the die on a plane parallel to it, the resulting marks will show as raised lines on the lowest portions of the coins produced from that die.

You solved your own riddle; well done. Die scrapes also occur on other denominations. The picture is of die scrapes on a New Mexico quarter.

For the help people. Being new to this I have a steep curve to learn and it's great to have patient people to help along the way.
