as a general rule dealers buy gold bullion coins from the public at melt {the price of gold} minus 10% and sell the same bullion coin at melt {the price of gold} plus 10%....some major dealers work on a smaller margin...say 71/2%...or as low as 5% for some preferred customers
your profit or loss will come over time by the increase or decrease in the value of gold... Traditionally gold and silver are purchased when they are dropping in price ..when their price is on the rise you hold or sell...when prices are going down you buy...in the long run you are working on an average purchase price....today gold is at 675.00 when it goes below that and while it's going down you buy when it rises you hold...you keep watching... when it's rising until it reaches new highs you hold or sell ....and when it starts to drops again and while its going down you buy.... when its going up you hold or sell.when it's going down you buy
