If it's got a name inside or it's otherwise returnable (ie. there's a 'lost' ad in the paper or something) I will attempt to return it. Call me a lefty, call me old school, whatever...it means more to them than it does to me. Golden Rule and all that... I actually did lose my wedding ring about 2 years ago and would give a lot to have it back!
Its weird these threads... its like people have the need to attach emotional feelings to a chunk of metal that our detectors were meant to find... it goes into my collection and if it doesn't I will sell it. some chunks are nicer than others.
