Be curious to know what you folks think of these. Assuming none of these are very valuable, if you need something here to fill a blank spot in your collection just let me know and I'll get it to you.
Again, there is nothing in your scans that will not turn up in most general world collections. I like the Mozambique, but then I have a soft spot for Mozambique (I already have these).The important question to me, at present, is where do you personally wish to go with all this?
You will get lots of advice as to how to do a), b) or c) but it is most important that you decide what your goal is up front, as you are doing your initial research. Maybe I am trying to rush you...but this is important. If you intend to sell, further advice will be totally different than if you intend to keep what you have and collect.
As a very simple example, and not intended to be binding, if you intend to collect, I would recommend that you purchase some Scott Catalogues, not more than 5 years old (you don't need this years version, and will get earlier sets at a considerable dlscount) , and some Stockbooks or Stock pages to house your stuff, especially that mass of "stuff in a box".
And you do have a lot of work ahead of you. My advice here would be, take your time and have fun, and slow down if you start to get bored - walk away for a day, or a week if you must, and return refreshed. Stamp collecting is a hobby, not a heart attack.
But for reselling, any "investment" in Stockbooks/pages or even Catalogues (just borrow some from your Library) may and probably will, cost you more than the resale value of your material. Just whack the lot up on eBay as a job lot, and get what you can, without spending to much time and effort - how much do you value your time?
give your future directions some thought before investing too much time and effort in something you may not want to continue. You may change your mind 6 months from now (don't we all? - take my ex wife, please - just take her), but you will have reasoned the whole thing out in advance, and used your judgement to make a considered decision.
There is, of course, the trap. Start studying these little beasties, and you, like many of us, discover that there is no escape from stamps, become obsessed, and never want to let go of any of them. But trust me, it's a fun obsession. And apart from our drinking habits, we are mostly otherwise normal.
