Science vs. PCGS Addendum: 1891-S Double Eagle.

This video shows that blind faith in a coin grading company results in a negative impact on the hobby and what it is supposed to be about...the COINS themselves. PCGS returned this double eagle as "authenticity unverifiable." ALL coin grading companies use subjective opinion to evaluate/grade coins. And in this case, and likely many others, a valid US coin would likely have been melted down or discarded b/c of it.
