If you buy a 24kt gold coin and alloy it yourself, it goes like
this, $665 current price of gold, 3% mark up on a coin from a coin
dealer=$684.95. Divide $684.95 by 24== $28.54 times 14 if you are
making 14kt, gives you $399.55 or $12.84 per gram. Todays price on
14kt from Stuller, who I do not think rips people off, charges
$14.13 per gram if you buy one ounce.
Stullers price $14.13 minus what you can alloy it for $12.84 you
save $1.29 per gram or $40.12 per ounce, plus any shipping charges.
Of course you have to buy alloy and pay for the shipping on that.
