Bullion bars are ingots of precious metal identified by weight, fineness and maker. Gold, silver, platinum and palladium bars are different materials, not interchangeable versions of one element. Retail bars bring measured metal into formats ranging from small gram pieces to larger ounce and kilogram sizes.
The ingot tradition and bullion standards
Casting metal into an identified ingot separates the metal’s weight from a coin’s denomination. Over time, bullion markets developed standards for the composition, dimensions and identification of wholesale bars. Retail bars are smaller products with their own specifications, even when made by a refiner also active in wholesale markets.
Poured, cast and minted bars
Casting forms molten metal in a mold. Minting uses prepared blanks and dies to produce defined markings and designs. Differences in surface texture can reflect the production method rather than a difference in purity. An assay measures composition; an assay package records product information. Neither is the same as a third-party coin grade.
What to check in this collection
Read both the fine metal quantity and the number of pieces included. A listing for several small bars is not the same format as one larger bar. Assay packaging, serial numbers and design details should be treated as product specific features rather than assumed for every bar from a refiner.
