Sammy Davis look out (just kidding) people collect (or use) antiques glass eyes. Sometimes my searches turn up some eye opening items that people are selling. This vintage glass eye that was attributed to the German army after WWI sold for $100! So make sure that when you are looking through those box lots that you don't make any incorrect assumptions on the values of the items you are looking at. You could easily look past a bargian like one of these.
