EXAMPLE: A person wants to sell their gold. They know it weighs 45.3 grams. They go to a Pawn Shop to see what the Pawn Shop is willing to pay, but the Pawn Shop only pays in Pennyweights, not grams.

HERE'S HOW: Be sure to weigh it, and Acid test it before putting it away and throwing away the box it came in!
