Ravens Super Bowl XXXV ring, Orioles 1970 World Series ring up for auction

A couple of championship rings from Baltimore teams you can't forget and players you might not remember are up for auction.

Former Ravens wide receiver Germany Thompson's Super Bowl XXXV ring, in its original presentation box, has been listed on Robert Edward Auctions with a $5,000 starting bid. Thompson was signed off the team's practice squad for the final three playoff games after tight end John Jones was injured. He was inactive for all three games and recorded no stats in his NFL career.

The ring has "a few minor nicks and is in Excellent to Mint condition overall," according to its lot description.

Orioles fans might have a better recall of Jim Hardin, whose 1970 World Series ring, also in its original presentation box, had a starting bid of $2,500 on Robert Edward Auctions. The right-hander played in 36 games for the Orioles in their championship season, starting 19 and going 6-5 with a 3.53 ERA. He was in Baltimore for five years and posted a 43-32 record and 3.18 ERA from 1967-1971.

"It should be noted that nearly all of the Baltimore Orioles 1970 World Series rings that have come to market in the past twenty years are either salesman's samples or those issued to front-office personnel," the lot description notes. "This is only the third example of a player's ring we can recall seeing at auction, making it an exceptionally rare and significant memento commemorating the Orioles' 1970 World Championship season."

Both auctions end April 30. Time to start checking in between your seat cushions for spare thousands.
