I have a 78 rpm Vynil record of Enrico Caruso in pristine condition and immaculate original sleeve i have foto if required what value could it realize .

Call Sothebys, because you don't want 2 go over 2, York Ave and get the run around. They'll be able over the phone if they are interested.

Contact Sotheby's directly. They may be able to answer your question and may even have a buyer, if you are so inclined. If not ask for recommendations.
