Gold bar guides
Gold bars cost less over the gold price than coins of the same weight, and bigger bars cost less per gram than small ones. A 1 oz bar is the most popular size. Choose a bar from a refiner on the LBMA Good Delivery list so it is easy to sell later.
Gold bars are the cheapest way to buy gold by weight, because premiums fall as bars get bigger. These guides cover each size and the refiners whose bars are easiest to sell.
