Almost all of my collection is stored in 2" x 2" cardboard holders that have clear Mylar plastic (not PVC) windows. You can buy non PVC clear plastic pages; they are more expensive, and they are not as clear, but this combination is far superior to my way of thinking. You put the 2x2's in such pages.
Mylar is the clear plastic material used for stamp and banknote albums.
The advantage of this combination is that you can write the details of each coin as you receive them, things like grade purchase price, and when obtained.
I have seen illustrated on this Forum plastic album pages for slabbed coins. Both types of pages could all fit into a common ring binder.
With this type of system, you can move the coins to a different area of the album, and the details relating to each coin move with the coin.
