Holland Gold sells only Gold bars which are produced by LBMA-accredited (London Bullion Market Association) refineries. The Good Delivery status is a quality mark that sets strict requirements for the production, weights and purity of gold bars, which ensures that the gold bars can be traded worldwide without further analysis.
All gold bars come with a certificate of authenticity. Please note that this is not a separate document but a part of the packaging. The LBMA quality mark can be seen on the bar for all bars. The stamp of the refinery and the gold content are also on the gold bar and the packaging.
