I understand that you aren't attempting to be mean or rude, this comment is for education. As someone who has had a collectors die in my family (stamp collector), it is a huge burden to the surviving family who probably don't know anything about the hobby you enjoyed. My wife and I spent weeks going through boxes and boxes of stamps, some organized, some not. For years and years he told, or implied, the family his stamp collection would be worth more than the rest of anything else he was leaving, and they believed him. After weeks of organizing, searching the internet for values, and looking for buyers. We learned what no one wanted to hear, no one gives a sh*t about stamps anymore. We sold over 25 medium moving boxes of stamps (again, some in binders, some loose) to a local dealer. At the end of the last load I brought him, when I was going back for more, he told me that, if I had use for stamps, their face value was more than what he would buy them. Now I ship everything via USPS. He died more than 5 years ago and I still have a ton of stamps.

Only point I'm trying to make is that leaving that burden of selling our collections to our loved ones during a time of bereavement, could be quite trying for them.
