Hello, Im a treasure seeker like you, I look in dumpsters, trash cans , GoodWill stores ,Flee markets!  This could happen to you! True story! A few months ago Looking for a Cool Valentines gift I went to my favorite GoodWill and found 5 Metal Stars w/ a reflector and the word Safety imposed on the bottom. I thought they could be for old bicycles, I bought 2 for $2.60 ea.. Went home and and at midnight was searching the Net for my stars, This is where it gets Good! I found 1 listed , Safety Star , with 3 hours to go it Sold for $660.00. Im now nuts,I have 2 and I know where 3 more are ,not much sleep, I got the other 3 at $2.60 ea. In the course of 3 weeks I made $1800.00    Another mans treasure is out there !    Tom Wage
