What Kind Of Storage Or Filing System Do You Have?

Thank you.
I just saw this which looks pretty cool a 84 Pieces 46 mm Coin Capsules, with Foam Gasket and Plastic Storage Organizer Box, Coins Holder.

And I hear and read so much here and there that certain things damage coins if they're stored a certain way for a certain period of time or if it's a particular type of material that they're stored in, or if it's stored in light blah blah blah.
The roles I just cracked open a couple tonight which I posted about I believe that the paper and due to how they were just the word I'd say cause the little damage if possible mildew or staining due to the packaging and storage you know I'm maybe not maybe it could have been the coins themselves I'm not a professional so I don't know.

Mylar flips in 20 pocket archival quality album pages.
Collection describes coinage history of all major World cultures, since the beginning of coinage 2600 years ago.

Each flip has all information relating the the coin
-price paid, and date when acquired,
-brief description of the coin, with relevant catalog numbers.
Collection arranged in two sub parts:
the most valuable coins are stored in a small album in date order, in a small safe,
The rest of the collection is a working reference collection also in date order, in 8 albums of about 160 coins each.

I also have a parallel supporting photo file system of all significantly valuable coins

Started the collection about 45 years ago with a Roman gold aureus. It is my intention to continue to grow the collection, until I die.

No supporting spreadsheet needed, with such a simple system of coinage description, history in date order, and an appropriate method of storage and display.

Not much different from what the British Museum uses, except that they store their coins with descriptive tickets in trays in cabinets.
The British Museum also has a supporting and very extensive data file and digital photo system needed for quick reference and to eliminate the need to handle particular coins unless necessary.
