You might remember that other former Ravens' had to do similar. Jamal Lewis got $50,000 for his while Damien Berry got $43,000 for his. The sale of Carr's ring includes a letter of authenticity from Carr according to Aaron Wilson of the Baltimore Sun
Carr was an undrafted free agent for the Ravens out of Alabama State in 2012 and eventually made his way to the practice squad. He was subsequently cut before the 2013 NFL season and hasn't played in the NFL since. However, Carr chose a good time to become a Raven as Baltimore would eventually make it's way to the Super Bowl against the San Francisco 49ers on Ray Lewis' final ride. Like most of the team, Carr received a ring for being a member of the organization despite not playing a regular season snap.
In what has become a regular appearance, Carr is just another former player with apparent money issues that is forced to give up something that few players ever achieve. Looking at Carr's former ring, he got everything out of it as it is marked up quite a bit and has some patina to it.
