I also keep my coins in albums (in 1.5"
flips so I can get more to the page). My
collection is quite focused which I guess makes planning easier. I've got a 3.5" fat (7lb
weight!)
album for my
Constantine issued coins (main focus), plus seperate albums for
his tetrarchic predecessors and peers, and for much earlier/later coins (e.g. greek,
kushan,
severan,
byzantine).
The way I have the main
Constantine album organized is by date then grouped into particular issues or dates, and I do leave a little space between these various groupings for both planned or unplanned
additions. The nice thing with a ring
binder is that you can always insert pages to expand a particular section - you don't need to reorganize the whole
album.
However, although I do try to plan ahead to leave space for new
additions, I also quite *like* reorganizing the
album, and find that each time I do a re-org I've learnt something from it - there's something to be gained from seeing all the coins and consecutive issues physically together.
