Going through and cleaning out moms house for sale. Downsizing since dad passed. I think it has more to do with financial consideration and she's having a hard time up and down the stairs, but won't admit to the last one.
Anyhow, got all the remaining lead and casting, smelting, reloading stuff. In the pile was 8-10 ingots as seen in the picture. They weigh about 8 to 8-1/2 pounds each. I can't deny it or scratch it with a nail. Most his other stuff is pure or COWW. Got those squared away. Even found some bar solder. This I just don't know. Ideas?
EDIT:
Title should read imperial marked ingot not superior.
