It just means you won’t know what brand of gold bar you are receiving. We offer bundles (or singles) of 10 ounce gold bars that are produced by different mints, each with the high industry standards you expect from GMRgold. You may receive a bar from PAMP Suisse, Engelhard, Credit Suisse, Johnson Matthey, Perth Mint, or another mint. It all depends on what we have in stock when you order. Rest assured any 10 oz brand name gold bar you buy will be 10 oz of .9999 fine gold.
