Marked on edge of ingot. This ingot will be in a sleeve to protect it. ART BARS & ROUNDS PRIOR TO 1982 ARE INFINITELY RARER AND MORE VALUABLE THAN LATER VARIETIES DUE TO THE HUGE MELTDOWN OF SO MANY DURING THE EARLY 80'S, AND RECENT YEARS WITH THE RISE OF SILVER PRICES AND ARE CONSIDERED MOST SOUGHT AFTER. Please make sure you do not have any additional costs. These charges are the buyers responsibility.
