Bicentennial Eisenhower $1 symmetrical scratches on Obverse

[DavidA]

I was wondering if anyone would know what could have caused the scratches outlining Eisenhower's face? They seem too perfect and symmetrical.

Thank you

They appear to be some minor scratches from die maintenance. Scratches are pretty normal on coinage that was abraded because of other issues such as clashes or damage during prep of the dies.

Thank you, does it devalue a coin?

If it tends to take away the appeal it may.
There are a select niche that might collect something like this, but they are few and far between. But they tend to look for massive polishing examples.
Normally these polishing lines are typically ignored by most collectors. They may have a little more negative effect if the coin were in a high (gem) BU state.
