Looking to expand upon the discussion of the following thread in the Numismatic Crime section.
https://goccf.com/t/194754Of course the appraisal fee will greatly depend on the size and value of the collection but I've always heard that a professional numismatist will charge approximately a $100 per hour for an detailed appraisal on company letterhead. I don't see how the appraiser in the above thread could possibly defend his charge of $26,000 for the appraisal of a $9,000 collection/accumulation. The coin dealers that I've seen do appraisals usually are able to go through a collection rather quickly, separating the common stuff from the items with more potential very efficiently.
