It must be the "luck of the draw". I purchased a set of Coker Classics for my '51 at least 10 years ago. I mounted them, and the fronts (185/75/R15's) needed no weights! The rears (225/75R15's) needed 1 3/4 ounces on one and 2 on the other. I have driven on them the whole time with no problems. This includes many trips of several hundred miles at freeway speeds.
Since they are now over 10 years old, I think I''ll have to get another set; they look great and still drive great, but radials age faster than bias plies.
I'll be buying another set. I once worked for an Irishman who always told me : "It's better to be lucky than smart".
