Hello,
My father passed away two years ago and I'm trying to help my mom liquidate my dad's stamp collection. I've been lurking and reading this site and quite a few others for the past couple of days and have learned quite a bit.
I'm tempted to sell on
ebay or one of the other stamp auction sites. I do have time, but I'd hate to waste it if it's not going to gain much more than going to a collector/buyer.
The collection includes:
Liberty Book -- almost all stamps from 1922 to 1988.
Almost all airmails from 1926 to 1985.
STS-8 Flight Cover (1983 Space Shuttle) -- 15 in original sealed/unopened envelope.
The Americana Series book -- 1970s stamps.
Birds & Flowers (Singer, 1982) - two postcard sets in books; four full sheets in a book.
Other assortments of books and sheets, mostly from the late 1970s to mid-1980s.
My dad was really into his collection. He took great care of it -- everything is in mounts or in sleeves and well maintained. Everything in the Liberty book and most everything else is unused.
Is there anything that's likely not worth trying to sell?
1. Would it be wise to try to online auction the early items, say up through the 1940s? I'm thinking I would do it by sheet.
2. Is it wise to remove stamps from mounts and photograph the gumming for online auctions?
3. Should I try to auction anything else?
4. Or am I just wasting time to not make much more than just going to a collector? I'm sorry I have so many questions and nothing to offer, but I really appreciate your help. If anyone has questions about hiring a mobile disc jockey, picking out dance music, or ballroom dancing, I can help you there, lol.

Thank you, thank you! I appreciate any and all advice!
