Vintage Phoenix Precious Metals 1 oz 999 Fine Silver Poured Loaf Bar – Lot of 15. Precious Metal Content per Unit. Total Precious Metal Content. These bars were made by Phoenix Precious Metals (PPM), a refiner active during the 1980s based out of Phoenix, Arizona. Other 1 oz, 5 oz, and 10 oz varieties have been observed, all with their distinguished phoenix logo. Though the total mintage is unknown, they are all believed to be quite scarce, and are highly sought after amongst collectors. All of these bars feature the classic loaf shape, some showing dark toning and/or minor contact marks. (Photos shown are stock, but all bars should be of the same appearance, condition, and quality).
