I have a Liberty 1957 silver dollar w/woman on front and eagle on back & I have a Liberty 1951 half dollar w/man on front and liberty bell on back
IIRC there was no Silver Dollar made in 1957--please post a photo. As for the other coin---we also really need photos of that one to because the value would depend on the grade---off the top of my head I would say it would be around $4 at lowest. Speedy
Comemeratives? I would say the dollar is PROBABLY around an ounce of .900 silver, so no less than 10 dollars? Half that for the other one. Just a guess, I really have no clue. -Rob
