Quick question about buying 90% coins for bullion - when they're minted they're .~715 oz to the dollar. What happens when they're worn? In general is the 'wear' just flattening of the detail or is there a substantial weight loss associated with the coins? If I buy a 100 oz bar I'm fairly confident it will be 100 oz. If I buy $100 face of generic 90% coin from, say APMEX or Provident, I don't know how close to 71.5 oz I'll actually be. Any thoughts are appreciated.
Thanks.
Thanks.
