Minted gold bars from Heraeus
For an extra charge, minted Heraeus gold bars can be purchased with an additional security feature, the Kinegram®, which is also visually appealing. They are available in six sizes: 1 g, 2 g, 5 g, 10 g, 20 g, and 1 oz. Kinebars are likewise packaged in the popular blister packs. These are made of PET, an environmentally friendly plastic, and the two welded seams make them particularly stable. Each is about the size of a credit card – 85 mm x 54 mm.
As of 2013 – The design of Heraeus bars has been repeatedly changed over the decades, so older bars may vary from this description.
