I am fairly new to collecting physical silver and today I picked up a 1 oz silver JM bar from my local Buy-Sell gold and silver/Gun shop. Wondering if there is any way to determine when the bar was made or age from the serial number?
Johnson Matthey silver bullion bars have an individual serial number on them, but they only stamped serial numbers on bars that were sold to commodity exchanges. Silver bar is typically not considered an exchange product, but was minted as a retail product.
