These bars from Valcambi are minted ingots. A minted ingot bar is produced using a different refining process than cast or poured bars. All 1 Kilo Valcambi Silver Bars in this listing are cut from rolled silver, and feature a higher quality finish and appearance. Brilliant designs are stamped onto minted ingots during the minting process. Each of the silver bars in this product listing features a rough, matte finish that creates an intriguing contrast between the refined features of the bars design, and its background field. All bars are shipped in sealed packaging with an assay card to verify authenticity. On the obverse side of the bar is the engraving of the Valcambi Suisse corporate logo at the top. The logo is followed by the bars weight, metal content, and purity. An assayers mark is engraved near the bottom of the bar, just above an individual serial number. The reverse face of the bar features the full corporate name of Valcambi Suisse engraved horizontally along the bar, with a background that features an ever expanding image of the Valcambi logo. Valcambi Suisse has more than 50 years of experience producing high quality precious metal bars. The mint was founded in 1961 in Balerna, Switzerland as Valori & Cambi. Throughout the past six decades, the mints ownership changed hands to Credit Suisse and European Gold Refiners, and is now owned by a precious metals group from India and Singapore.
