Hi Clarence, You might try to find a stamp club near you. Many clubs have members who would be happy to offer some advice on what you have and how best to sell it. It can be a little overwhelming when you first confront a large collection without much background in the hobby. If you enter the words "
inherited collection " in the search box, you will find a number of threads from people who have had this experience before you and some good general advice. Good luck.
