Berry said a friend put the ring up for sale without his knowledge, selling the ring to an undisclosed third party that later sold it to Goldin Auctions.
"I would never knowingly sell my Super Bowl ring," Berry said. "I'm not that kind of guy. That's not me. The ring means a lot to me and I want to do whatever it takes to get it back. This isn't what I'm about."
However, Ken Goldin, the founder of Goldin Auctions, told The Baltimore Sun on Saturday night that he has a copy of a sales agreement with Berry that includes witnessed, notarized documents for a chain of custody that will be made available to the winning bidder of an online auction conducted through www.GoldinAuctions.com.
Goldin said that his company conducts extensive research and verification of all items, and wouldn't sell anything that it's not authorized to make available for auctions.
A source familiar with Goldin Auctions' business practices said the company conducts extensive background checks to ensure that there's paperwork backing up the legality of all sales.
The minimum bid for Berry's ring -- pictured here on the Goldin Auctions website -- is $15,000. As of Saturday night, the highest of five bids was $36,603.
A former University of Miami player, Berry spent the 2012 season on injured reserve with the Ravens before being cut prior to the start of the 2013 regular season.
Berry expressed embarrassment about the ring being up for sale.
"This isn't a good look, I know that, but I swear this didn't start with me," Berry said. "I have a lawyer who's working with me to try to get the ring back. I was shocked when people starting coming at me on Twitter about what's up with my Super Bowl ring. It's definitely upsetting, but everything will be all right."
The winter auction also includes former Ravens linebacker Jamie Sharper's Super Bowl XXXV ring, former Ravens running back Jamal Lewis' 2000 Super Bowl trophy and former Baltimore Colts defensive back and kick returner Leonard Lyles' 1958 NFL championship ring.
There are no bids yet on Lewis' personal trophy, but four bids have been entered for Sharper's ring, with a high of is $14,641.
Goldin Auctions says it has sold more than $600 million worth of sports memorabilia, including a Honus Wagner T206 card for a sale of $2.1 million in 2012.
“This is a rare opportunity for a Ravens fans or a collector to own a Super Bowl ring less than a year after it was earned,” Gold said in a statement announcing the auction. “NFL Championship rings and Super Bowl rings are coveted by collectors because it is rare for them to become available. That is why we are so excited to offer these unique finds in our 2014 Winter Auction.”Copyright © 2015, The Baltimore Sun
