This is a matter of personal preference as well as your investment plan and overall economic situation. While bullion bars are generally cheaper in terms of premium over precious metals content, they are also larger (less divisible) and may in a severe situation be not as easy to sell as widely reckognized bullion coins. With large amounts to be invested, holding bullion bars makes sense. Medium-sized 100 gram gold bullion bars have almost the same low premium as the larger Kilobar variety and may thus be the choice for average investors. Smaller than 100 gram bars are not usually recommended for physical bullion investment purposes. Bullion coins have the added advantage of superb fungibility, particularly the popular internationally traded coins. In silver, it should be noted that silver bullion coins are treated more favorably than silver bullion bars and that there are a few more countries having silver bullion coins either totally exempt from VAT or sales tax or applying a low rate (e. g. 7% in Germany). This fact may also affect whether you buy bullion bars or bullion coins. (For details, see Do I Have to Pay Sales Tax… section, above.)
