Can't find this coin on cuds-on-coins.com or other sites. This is an obvious error of some sort so looking to the old and wise... on this site for your remarks. Thanks.
That line under TRUST is just a plating blister as stated. Your cent is zinc and coated with a thin layer of copper. This is very common and commands no extra premium.
As stated, poor plating issues on lousy Zincoln cents. NAV = NO ADDED VALUE, heck, hardly worth a cent, in my book.
Once again you folks have ed-u-ma-cated this old man. So sad.... been roll hunting two boxes of cents and not making much cents at this time... lol
