For those investors buying silver bars online, JM Bullion has a unique opportunity in this listing of Valcambi Cast Silver Bars. Many silver bar programs come with serial numbers for individual pieces, but you rarely have the chance to pick from a specific serial number range. In this listing, youll know the range of possible serial numbers youll be purchasing. Each 10 oz Valcambi Cast Silver Bar in this product listing is individually sealed in plastic. Included with your purchase is an assay card from Valcambi Suisse. This card has the mark of a certified assayer with the identifying hallmarks of the bar included. On the card, you will find the matching weight, purity, metal content, and serial number for each piece. Cast silver bars are a throwback to the original production processes for gold and silver bars. Long before machines aided in the production of highly-refined minted ingots with detail designs, produced from gold and silver for the purposes of storing national or personal wealth were made in a simpler process. The metals were first melted down and then poured into prefabricated molds to create a finished shape. Todays cast silver bars are made in much the same way. On the obverse of 10 oz Valcambi Cast Silver Bars, you will find the identifying hallmarks of the bar. All markings are arranged in portrait orientation on this field of the bar. The mint name and logo feature at the top, with the weight, purity, and metal content noted along the right edge. An assayers mark is at the bottom, along with the unique serial number. Please note, the serial numbers start with AA and, in this listing, are limited to numbers 101 to 500. The reverse of these 10 oz Cast Silver Bars is blank.
