Sellers of collectibles and antiques get bombarded with nitpicks and
corrections. Often these are right, but often they are wrong. And

me a comment like this, I would think "Oh, it's Noel, he knows his
stuff. I will deal with this". But if someone I do not know did the
same, I would maybe send a thank you note, think about it for a minute
or so to see if investing a bunch of research time is worth it, and
likely do nothing. Let the buyers figure it out.
