Say for the sake of simplicity (and because I am too lazy to look it up)... Just say that spot is $15.00 an ounce today. Multiply that figure by the amount of silver in the half (.36169 oz)... That is the arithmetic that tells you the raw value of the silver in the half or $5.43..... Did that help or did I confuse it more?
Don't worry about it Chris. Some folks feel important correcting others over nothing. Dear God, don't ever make a spelling mistake.
