Heraeus produces cast bars in four sizes: 100 g, 250 g, 500 g, 1,000 g. Like all Heraeus gold bars the 100 g bar carries a serial number. The purity is 999.9. It comes with a certificate which is jointly with the bar sealed in plastic foil.
The 100 g bar is the only gold bar that is available both as minted and cast bar.
