A week after the Seahawks won the right to make a bunch of Super Bowl rings, more than a few past Super Bowl rings have been sold via auction.

According to Aaron Wilson of the Baltimore Sun, the stripped-down Zirconia ring issued to Patriots Spygate videographer Matt Estrella went for $15,810. Real rings brought in much more.

The Super Bowl XXXV ring issued to former Ravens linebacker Jamie Sharper went for $36,883. Former Ravens running back Damien Berry’s Super Bowl XLVII ring went for $43,008.
