Can you help identify the following bullion rounds. Thank you in advance.
1. walking liberty replica: 39.1 mm diameter., 2.96 mm thick, 31.1 g weight. I saw one in the catalog except for having a HM below the shield being to the right rather than the left as showed in the catalog.
2. Liberty draped bust replica, one Troy ounce of .999 fine silver: 39.1 mm diameter., 2.9 mm thick, 31.2 g weight.

3. American coin and vault, one Troy ounce of .999 fine silver: 38.6 mm diameter., 3.16 mm thick, 31.3 g weight.

4. seated liberty replica, one Troy ounce of .999 fine silver: 39.26 mm diameter, 2.86 mm thick, 31.16 g weight. I’ve had this one since the early 1980s.
