History – The Quarter Kilo in the Swiss Banking World
The 250 gram bar has deep roots in Swiss private banking. As numbered account holders at Geneva and Zurich institutions began accumulating physical gold reserves from the 1960s onwards, Swiss refineries standardised a range of cast bars: 100g, 250g, 500g and 1,000g. These four weights became the backbone of Swiss vault storage programmes and are still the standard formats used in professional bullion vaults worldwide.
Valcambi in Balerna and Argor-Heraeus in Mendrisio – both located in the Italian-speaking Canton of Ticino, near the Swiss-Italian border – produced the 250 gram cast bars that filled these vaults. The characteristic rough, crystalline surface of a cast bar (compared to the smooth, mirror-like finish of a minted bar) is the result of pouring molten fine gold into a bar mould and allowing it to cool naturally.
Why are 250 gram bars always cast rather than minted?
At this weight, the pressure required for precision minting becomes economically impractical. Cast bars allow equally precise weight and fineness with lower production costs – the savings are passed on in lower premiums. Both formats carry identical gold content and buyback value.
Does tarnishing on a cast gold bar reduce its value?
No – gold does not tarnish (unlike silver). Any discolouration on a gold bar is superficial and has no effect on purity, weight or buyback price.
