I am not familiar with IC fabrication and manufacturing practices and was seeking information regarding IC pins with noticeable scuffs in the top portion of the lead. Is this a result of manufacturing process or is this a prior used DIP IC? I want to avoid relying on used parts or potentially duds. I do not see scuffs on the pins that would penetrate into board or socket which would be obvious to a prior use. Any advice on this would be appreciated. I attached a photo of IC with this scuffing/scratching affect.
