Ive been told by many dealers that the 1oz cast bar is essentially the easiest for them to move. I dont disagree, its a common and recognisable size. Perhaps the cohort of people with cash that visit dealers are not exactly the same cohort that are trading and trying to get bang for buck on the forums. For big money, why would you bother with fractionals. Bars 1oz+ would be the way to go, especially for interstate/international transport. But for the family trying to put a bit of savings a side each week into metals, you would be hard pressed to get them to look at anything bigger than 1/4. When i started stacking my first buys were 1oz sized, but it didnt take me long to see that i was going to have trouble moving them quickly without accepting dealer buy back rates. I made the move to all 1/10 and smaller. Converting my stack cost me the equivalent of 1/10 oz of gold, but the rise in price quickly recovered that and made it a sensible move. I just wish I had more time/funds to commit before this bull market, but im sure we all wish the same. If gold becomes unaffordable, I will have to look elsewhere to silver or bullets and beans for inflation protection.
