What are 100g silver bars?
The 100g silver bar is one of the most popular mid-range sizes for silver investors, striking a balance between the affordability of smaller bars and the value-per-gram efficiency of larger holdings. Containing 3.215 troy ounces of fine silver, a 100g bar offers substantial weight while remaining easy to handle, store, and resell.

About the refiners
Our 100g silver bars are produced by two of the world's most respected refiners:
Valcambi: Founded in 1961 in Switzerland, Valcambi is one of the most prestigious LBMA Good Delivery refiners in the world. Valcambi pioneered the CombiBar® concept, allowing investors to break a larger bar into smaller, transferable units — ideal for flexible silver stacking.
Nadir Metal Rafineri: Established in 1986, Nadir is a Turkish LBMA-accredited refinery recognised for producing high-purity 999 silver bars at highly competitive premiums. Its 100g minted bars are a popular choice for cost-conscious investors.
Design and features
100g silver bars are produced in two main formats:
- Minted bars: Solid silver bars stamped with the refiner's hallmark, weight, purity, and unique serial number, supplied in tamper-evident assay packaging.
- CombiBars®: Each 100g CombiBar is pre-divided into 10 x 10g or 100 x 1g units that can be snapped apart, giving investors maximum flexibility for partial resale, gifting, or barter.
All 100g silver bars are sealed in protective packaging to preserve condition and authenticate provenance.
