Here is a short video that shows both sides of several Coca-Cola fine silver 75 th Anniversary bars and rounds. Most are bars, and most are 1 Troy ounce of fine silver. These were minted starting in 1973, and ended in the 1980s. They celebrate the 75 th Anniversary of Coca-Cola bottling plants, and each plant involved has its unique issue, some with very low mintages.
Some bars are very ornate, as you can see from the ones shown.
