Hello! Around a year and a half ago one of my mother's elderly Facebook friends passed away, she and my mother talked a fair bit, and my mother told her I liked history and would probably be interested in stamps. The lady was a life long stamp collector and shortly after her passing a few things arrived at the house:
* A black handbag
* 3 US Liberty Stamp Albums of varying sizes
* A little green box
All filled with stamps, with a lot of them being foreign.
I didn't have much room at the time so I set them aside, and dragged my feet getting back to them, lately I went through and cleaned everything during quarantine and now is the ideal time for me to get into it. It touched me that she would send this to me, so I intend to keep building on it. I likewise understand that the odds are 1/10000 that I'm not sitting on gold, but a collection of "I'll give you x for the lot of 'em" stamps.
I'm going to post some images as well as a general description of the what's contained, if you see something you want a closer look at for any reason/more details I'll happily comply. I'm interested in learning more about these so if there's any light at all you could shed on anything in here I would be grateful.
For those less interested in the images than the questions I have for getting started, I'll post them here instead of under the image spam to come:
1. Are there some generally good resources I should be aware of?
2. What are the bad habits/practices/taboos to be aware of before I slip up?
3. What are some options I Have for how to take these stamps from their current state in a million little envelopes and putting them onto something more displayable and organized?
4. Any general advice is also helpful!
Now onto the collection itself!

In the thinnest of the liberty binders were these folders. I think their covers speak for themselves.

A look at the inside of one of these (1972), from what I can tell they all have their stamps.

I didn't take it at a good angle but there was also a folder containing a bunch of sheets like on the right for various nations. From a quick look through it's about 70% European, 20% British Empire, 10% misc.

All three of the liberty albums contain American Album pages, a good 90% are blank. It's about 1 1/2 binder of American history and the third binder being 1/2 filled and focusing on media and miscellany. The lady who collected these put the great condition stamps in black protectors, but most pages are only 10-40% completed amongst the ones that have stamps at all.

Now onto the handbag!

Though the cover says Russia the folder is something like 30% Austrian, 20% German, 30% misc eastern europe, and 20% Russia. These stamps all were out of their envelopes and loose in the folder, none look damaged from it thankfully.

I don't know what this is held in, but the stamps here are labeled differently than anything else in the box (as in they're labeled at all), figured I'd mention it. These were in its own folder.

There was a little Christmas card box in the bag that contained the jackpot of the whole collection, I'm frankly scared to touch these but as expected they're almost entirely european.

The envelopes underneath contain stamps in condition like these (Canada).

from top left to bottom right: 1$ collection of painting stamps and flower stamps, folder containing a large quantity of British Empire stamps, mostly focusing on the African and Oceanic parts (South Africa and Australia make up half the folder), A Stamp Identification help book, some stuff from an auction she went to, two envelopes of stamps (100 communist china and 25 cambodia) as well as 25 Malaya/Malaysia, a neat little colour guide, and a bunch of polish stamps in an unlabeled envelope.

Thankfully the bag also contained a bunch of stuff to (hopefully) help move these into something more organized.

The green box!

In the front is a bunch of these envelopes of stamps, there's a decent amount of american stamps in this portion, especially compared to the rest of the collection.

The middle is a bunch of note cards listing nations that fall under the letters above, but nothing else in them. At the back here are more envelopes that are about the same breakdown as the rest of the collection. 70% Europe, 20% British Empire, and 10% misc.
I apologize if this post breaks any sort of rule I missed.
