Die Damage, new dies
LEE 44 magnum, full length sizing die. Ran 60 pieces of brand new starline through it. Afterwords noticed that each case has a scratch around the whole case, same spot on each one. Not found on un sized brass.
My question is, is it worth trying to sand it out with sand paper and emory cloth, or just bite the bullet and get myself a new set from another company

Greetings,
You have experienced "Galling".
The new brass is chemically clean and has welded little bits to the Carbide ring of the sizing die.
The brass that is stuck/welded to the Carbide ring can likely be removed with some fine steel wool and oil.
Cheers,
Dave

The whole carbide ring has been affected. Sanding won’t help. Send it to Lee with a sample case. They’ll either polish it out or replace the die.

I had the carbide ring in a factory crimp die crack like you slice a bagel. Lee replaced the die

New Starline brass can be very difficult to size. I always use Hornady OneShot case lube on new Starline brass. Subsequent sizings generally don't require it.

Pictures would help
