Are sales of gold and silver registered?
I think gold has to be. Have to be careful if you do this stuff out in public. Remember Tom Noe? He had a bunch of coins in his car and then dropped his kids off and in the five minutes he was gone, thieves broke into his car and stole hundreds of thousands of dollars worth of coins (they basically followed him around all day, hoping he'd stop, and that the car would be left unattended, even just for five minutes).
