Stamp collection valuation

Do you know where I might sell my dad’s old stamp collection? I don’t know anything about stamps, so I have to hope they are honest.
Thank you.

Terry Says:  This is really a tough question.  I know coin dealers I trust, but I don’t have a personal recommendation on a stamp dealer, or philatelist.  We both know that an appraiser could easily switch out a valuable stamp, or simply classify it wrongly, and not give you a fair price for it.  My best recommendation is to give you alink to the website of thehttps://www.americanstampdealer.com/   There you can search a reputable dealer in your area.
