Wish Dansco had done a better job with the binding on those albums; so often, I see examples where the pages have completely separated!
... and it might be the last one you see for a very good while. To be honest, I didn't even know that title existed. Show us the inside and some of the pages, if you feel like it. I once had all of the Irish predecimal series in three Dansco albums. Those are scarce-ish and a little hard to find nowadays, but probably nowhere near as rare as that New Zealand album.
Here is the inside of the album. The 1948 came with it so all the other coins were transferred from my Bertrand folder. The Bertrand folder is in such bad shape I tossed it wasn't even worth giving away. This folder is listed in Thomas Moll's book Guide to Vintage Coin Folders and Albums. There is also a Shilling/Florin version but I've never seen that one for sale. For that folder I cut apart an Australian Florin and Shilling folders and taped them together. I then put stickers over the dates and wrote the New Zealand dates on them.
