I'm curious to know what percentage of catalog to expect an honest dealer to pay for my U.S. collection. My collection begins at Scott #1 and continues through to mid 60's. I realize that most stamps, with the exception of Zeppelins, from 1930s on are good for postage. My stamps are for the most part used from 1889 on back and mint from 1890 on. My commemoratives are complete. Airmails are also complete. For the most part, if a stamp catalogs less than $500, I have it. My stamps are primarily VF and most issues valued in excess of $100 come with certs from PF or PSE which state that they are genuine and without fault or alterations. My belief is that sale to a dealer is going to yield the least amount while auctioning and direct sale on
ebay would garner the most. I'm 68 and in excellent health physically an financially. I'm not really considering selling at this time, but I'm curious as to the answer as I have seen this question many times, but the person asking the question usually has a collection that is modern and of little or no resale value.
