The 10-ounce gold bullion bar of at least .995 fine purity is the standard industry unit. It is traditionally used for trading and storage, and can also be taken for personal delivery. Each gold bar is hallmarked by a leading refiner to certify weight and purity.

And finally, for those who want the finest investment-grade gold bullion bars available, we proudly offer the exclusive Monex-certified and convertible 10-ounce gold bullion ingot...composed of pure .9999 (or "four-nines") fine gold bullion—among the purest gold bullion bars available to investors today. Each bar is certified, with its weight and purity guaranteed by Monex, and each bar is further hallmarked by Heraeus, one of the world's leading refiners, and the 800 year-old Austrian Mint, one of the world's leading minting institutions.

Gold bullion bars are real, tangible assets, and throughout history, have been an ideal store of value and an excellent hedge against inflation, deflation and political uncertainty. They are extremely liquid investments, easily stored and transported, and can be a uniquely private way to preserve one's wealth.
