I thank any replies in advance, I am just throwing ideas around in my head. I own a couple of Goldies but am increasingly thinking of physical, my questions are:

1. Should I be buying 1oz/10oz bars over 1oz coins, and if coins are considered better which ones should I hunt down and which ones should I stay away from if any. Is re-sale of bars vs coins any major difference?

2. Obviously the $AU is gaining strength back on the $US atm, what are the thoughts of holding off for a while until we reach a bit more strength, which in turn will reduce the amount to be paid???

Thanks, just throwing it out there as I have not bought physical before.
