Currently if I was to buy 10 10oz bars it would cost me $46 more than buying 1 100oz. selling back to the mint would get me the same amount. Its about 3% more expensive for the smaller bars. The spreads are quite large but not much can be done about that.
I'm hoping when its time to sell i'll have a better option than selling back to the mint. The way things are going now i'll probably swap it for a couple of chooks.
