I can't and I doubt they can either.
The outer part of a 40% half dollar is 80% silver.
The color difference between 80% and 90% is small and easily fooled by dirt on a 90%er or a shiny 40%er.
They have a fifty/fifty chance of getting it right but I bet a rigorous test would should plenty of errors.
HH!!
