Who makes the bars and rounds.

The Swiss refiner behind the Lady Fortuna bar, made in gold from a single gram upward and in silver, sealed in its assay card. Its Lunar bars carry a new zodiac animal each year, and its Veriscan system identifies a bar by matching a photo of its surface to the one PAMP recorded at the refinery.

Minted and cast bars from Balerna, Switzerland, and the CombiBar: a bar scored to snap into small units, first made as a 50 g gold bar in 2011. It pairs a larger bar's premium with the option of selling a gram at a time.

The Mendrisio refiner whose minted Kinebar carries a KINEGRAM hologram set into the metal as it is struck; Argor-Heraeus says it is the only refiner licensed to use it on bullion. Each minted bar is sealed in an assay card.

Minted bars come in a serial-numbered card that shows VOID if opened; cast bars are stamped with the swan, weight, purity and serial. The 1 oz silver bar hides a tiny P in the last 9 of “9999 FINE SILVER”. The Perth Mint's coins are on the silver and gold pages.

The refiner in Salt Lake City and Brampton, Ontario, that took over Johnson Matthey's gold and silver refining in 2015. It makes minted and cast bars in both metals.

A private mint in Henderson, Nevada, founded in 1979, making silver rounds and bars. Its bullion carries Mint Mark SI, a micro-engraved security mark that shows up only through Sunshine's decoder lens.

A Winchester, Indiana maker striking its own silver since 1973. Its struck bars carry the prospector and burro; its poured Pony bars are cast and hand-stamped.

Headquartered in Casper, Wyoming, and founded in 2008. Its Stacker bars interlock and each carries a serial number; its gold comes in Certi-Lock, a tamper-evident card you can verify online.

Johnson Matthey sold its gold and silver refining to Asahi in 2015, so no new JM bars are made. They still trade, and are sold here as secondary-market bars priced on their metal.
