Hi All, I am look at buying some gold, but not sure what is the best way to go when it comes to sizes... I am thinking 3 x 1oz bars, or 2 x 50gr bars, or 1 x 100gr bar. I will also be picking up a kilo of silver, but for now just wondering what is the best way to go for the gold, as in ease of selling and returns later down the track. Also how accurate is XRF testing on the larger bars (the 100gr bars) ? If the bar clear the XRF test, is that a 100% garantee. Also I will buying from a mint authorised distributer. Any suggetsions?
