Cover art for Nothing Man lyrics by Bruce Springsteen

Super song. This is a song about someone coming back home, who survived a terrible tragedy, whether it's just after 9/11, after a war, or after some other tragic explosion. He's probably severely injured and is honored as a hero in his hometown paper for his specific act of duty, though he doesn't feel like a hero.
While his life has dramatically changed as a result, life goes on as usual in his hometown. In the last verse, he's drinking at a bar talking with the locals, who appreciate his service. "Pearl and silver". most likely is his handgun, which can end his torment, although it could be a necklace with a cross signifying the death of Jesus as "courage you can understand".
"Nothing man" symbolizes someone who doesn't feel special or significant although he is honored by people for his heroism.
