Overview
A rare vintage 1-kilogram poured silver bullion bar, marked with the prestigious 'Banque Nationale de Paris' (BNP) and 'Anvers' (Antwerp) insignia. Stamped with a unique serial number (106167), the 'BJA Essayeur Fondeur' assayer mark, and a purity of 999.9 fine silver, this bar represents a bygone era of European banking history.
Story
In the 1970s, European banks routinely cast their own branded bullion bars for private wealth storage. This bar links the historic diamond and financial hub of Antwerp (Anvers) directly to the Banque Nationale de Paris. It survived decades of melting pots to remain a tangible piece of Cold War-era financial history.
Maker / Origin
The bar features the mark of BJA (Banque Jouire d'Anvers / Essayeur Fondeur), a highly respected Belgian refining and banking entity operating in Antwerp's historic financial district. Their stamped bars are highly collectible today because most were melted down during silver market spikes, leaving very few intact specimens for collectors.
Condition & Value
The bar shows a beautiful, natural warm grey patina consistent with age, with minor handling marks and surface abrasions that do not affect the legibility of the stamps. This original, unpolished state is highly desirable to vintage bullion collectors; cleaning or polishing the bar would actually reduce its numismatic premium.
