I have 44 of these sterling silver ingots. All are still factory sealed on the card. No certificate of authenticity. There are 43 information cards. I keep these in a cardboard box. Each one is 0.67 troy oz of solid sterling silver. Each ingot is less than 1 troy ounce. Old US coins are 90% silver. Sterling silver is 92.5% silver.
These are not taken out of their original SEALED factory packaging. It's rare to find these in this condition. Price is firm.
