You can purchase Heraeus platinum bars in four sizes, from 1 oz to 1,000 g. The bars are delivered without certificates. They do not carry a serial number except for the 1 kg bars (produced since 2013). The number on the 1 kg bars consists of the year of production, a letter, and numbers. All our platinum bars are minted and individually sealed in plastic.
As of 2013 – The design of Heraeus bars has been repeatedly changed over the decades, so older bars may vary from this description.
