Scottsdale Mint 5 oz Silver Button – 5 Troy Ounces. No two bars are cast alike and the deep stamped logo solidly imprints the Scottsdale Lion into the center of this beautiful piece of bullion. Silver buttons have their origins in the mining industry and this product represents Scottsdale Mint’s homage to the made-and-crafted style of bullion. It’s not a coin. It’s not a round. It’s pure silver. Product dimensions can differ slightly and this item is not perfectly round. It is the product of molten metal taken straight from the furnace and machine stamped with an indelible strike. Make the Scottsdale Silver Button part of your collection today! Diameter: 50.50 mm.
