Calculate the price per gram
Divide the delivered price by declared fine-gold weight. Illustrative arithmetic, not a market quote: at 100 USD per gram of fine gold, 31.1035 g gives a hypothetical metal value of 3,110.35 USD. A real offer adds a premium and delivery. If the stated weight is gross weight, calculate fine-gold weight first.
US bullion quotes commonly use troy ounces. Divide the dollar quote per troy ounce by 31.1035 to compare it with a gram-based reference, using quotes from the same time. This conversion does not include the seller’s premium.
Buying and delivery · USA
For a United States purchase, compare the total in US dollars delivered to the same ZIP code. A gram-denominated bar and an ounce-denominated coin should be compared using fine-gold content, not their ticket prices.
Confirm delivery to your state, insured shipping, signature requirements and the seller’s payment conditions. Check any sales tax shown for your delivery address and avoid assuming that a price seen for another state is your checkout total.
