You will enjoy this DCB.  My wife likes to go yard sale shopping.  Does pretty well looking for items with gold and silver she can scrap.  A couple weeks ago she is going through some costume jewelry and comes across a Tiffany's brooch marked 750.  She buys it for .25.  Scrap alone on that thing is $850.  About an once of 18k gold.  Now that's some return.  Oh and looking a what some have sold at auction, upwards of $1800.  Got to love it.
