Gold is too expensive for the average investor and copper bullion is sold at way more than spot price.
Gold went down but not as much as silver did, so leverage wise, silver is a better investment. Once silver would bounce back with gold, it'll go up more in a percentage amount. Copper pennies are good, but then, you might have problems selling them.
MAKE SURE YOU GET PHYSICAL SILVER IN YOUR OWN POSSESSION. Don't Buy SLV, or Futures or Pooled Accounts or any other BS paper silver product .Remember anything on paper is worth the paper it is written on. Go Long Stay long the bull market have even started yet
