5oz Ainslie Silver Bullion. The 5 oz Ainslie Silver Bar strikes a nice balance of small size at an affordable price. The sleek and compact design makes the bar very portable. Along with the 10oz and 1/2kg, the 5oz is a great way to’round out’ positions that already include larger holdings of 1oz and 1kg denominations. The 5 oz Ainslie Silver Bars are cast bars and each piece has a slightly unique surface pattern. Each silver bar is struck with the Ainslie Bullion logo, along with its weight and purity. Ainslie Bullion commenced trading over 50 years ago which makes it the oldest bullion company in Queensland and over the years it has become one of the largest bullion companies in Australia. Ainslie Bullion produces a large range of high quality gold and silver bullion bars widely recognised, accepted and indeed sought after throughout Australia.
