Not a lot of “O” box, but here are some of the more interesting “O” ingots I’ve collected over the years.

OIO is one that has been a mystery. They are beautifully done and I’ve seen them in 1 oz, 10 oz and even a few larger sizes. They are fairly scarce.

Oregon Gold and Silver, OGS, is another really cool old refiner. They use a mold that is nearly identical to the Brown Materials and Golden Analytical pieces. They mainly came in 10 oz, but I’ve seen a 5 oz and I own a 2 oz piece that I’ll post in my “smalls” blog later. These are really cool bars.

Oxford has been around for more than 40 years now and still operates today out of Anchorage, Alaska. They made bars ranging from one oz commercial pressed bars to poured bars mainly found in 5 and 10 oz class, but these bars have become quite scarce, particularly the high premium 5 oz class. Heres a link to their website. https://www.oxfordmetals.com
