Thank you Going Postal, I'm glad to be here.

I am in northern Ontario. The collection is mostly all Canadian stamps organized by 2 small cardboard boxes and 1 small cedar chest/box, while there are thousands of stamps here, there isn't "totes upon totes of stuff". The cardboard boxes contain ziplock bags organized by "theme" or "place outside Canada", these are all used stamps mostly all removed from their envelopes, but some were on small remains of the envelopes. Some of these I have removed from the piece of envelope while others remain.
A significant amount of the used stamps are from places that my grandpa and mom lived, so any legible markings on the remains of envelopes were not touched because this collection isn't about money, it's sentimental. He has a couple intact envelopes but I haven't looked at those yet - and there is only a couple. Everything from the 2 cardboard boxes is being removed from Ziplock bags and going into lighthouse stockbooks, that's what I'm working on now.
I have only looked at some of the items in the cedar box, this box is mostly all mint stamps. Full sheets are on the bottom and are separated between each one with various materials - wax paper & some kind of soft smooth tissue like paper - not glassine. The cedar box seems to contain : Canadian mint sheets, Canadian souvenir sheets (Not the highly picturized ones that
Canada Post currently sells today, but like smaller mint sheets.), glassine envelopes containing mint stamps, "plastic"
Canada Post packaging with mint Blocks (?!? not sure if my terms are correct yet), mint strips and blocks not in plastic, mint sets of "10 stamps" that you would buy to put on envelopes, some are opened some are still sealed, and some various "packs" such as Canadian Tire, Winnie the Pooh (I think), "newer" souvenir cards like Princess Di after she passed, and some Easter Seals / Lung Association sheets. Some of the stamps in the cedar box have been exposed to humidity, nothing seems stuck together, but some mint stamps have curled a bit.
I believe the mint sheets are for the most part more recent than the bulk of the used stamps, it seems grandpas collection would have evolved over time to include mint stamps. My mom did continue the collection but mostly (it seems) continued tearing stamps off of envelopes for the Ziplock baggies, she is the one that organized the themes into baggies I have no idea what grandpas storage for these would have been, but it's highly unlikely to be Ziplock baggies he was very serious about "proper materials" IE: cedar box etc.
There isn't a single album / stockbook in the original collection, however I did find an old, partially used, package of "hinged mounts", so I am quite sure that he did have albums at some point in time.
For everything other than the full mint sheets in the cedar box I'm planning on putting those into Vario binders / pages. I haven't found a cost efficient solution for the full mint sheets yet - a single 24 page "mint sheet BOGA album" won't come close to holding all of these, with Christmas sales being over I won't buy multiple BOGA albums, maybe next year. Eventually once everything is organized I would love to find/build/buy a cedar cupboard of sorts to put the albums inside, as a 'nod' to grandpa and to mom.
