in regard to expensive things, not bikes or cars, a person can buy a flute, yes, a flute, that has a layer of silver for sound projection, and a layer of gold for warmth of sound. It is made by an American flute maker and sells for nearly $30,000. Yes I got the zero's right. Maybe I'll just sell my house and car and all my personal posessions and buy one and sit out on the street playing it with the case open for people to throw money into.
