No, why? Weights are typically used for authentication purposes, and I don’t think that is an issue here.
I believe weight is a good indicator of tapered planchet errors, but I am not an expert in rolling errors.
Ahh. I think I own a good, inexpensive one if you are curious. You might get good use out of it. How sensitive of a scale do you have?
I see. That probably won't do the job. I will try to see what my scale is, it might be $15-$20 on Amazon. There might be other ways to tell a tapered planchet, though.
