What is this, a charm or other piece of jewelry? Crown coins are silver and much heavier than 5 grams. But it doesn't really matter. 10k gold is 41.666% pure gold. So you multiply that by 5 grams to get 2.083 grams of pure gold.
There are 31.1 grams in a Troy ounce, the standard measurement for pricing gold. Divide 2.083 by 31.1 to get .06698 Troy ounce.
The current spot price of gold (Friday's market close) is $1,216 per Troy ounce. Multiply that by .06698.
The 'melt' value of the piece is $81.45. You would not get that much for it if selling to a shop. They will pay 90% or less. You might get more selling it for what it is than selling it as just gold, on eBay or Craigslist. Depends on how attractive a piece it is.
Its 10 karat and 5 grams. How much would that be?
