$3,080 USD

Available for sale is a Vintage Johnson Matthey 100 oz .999 Silver Poured Bar. This bar has an upside down 8 digit in front of the serial, it is odd as in is not just a skipped digit, if it was it would be the same style as the other digits though it is difference. Possibly a unique example?
