Hi! So the album itself is quite scarce (out of print), plus you've got the modern dollar coins there as well. I'm going to go out on a limb here and say that you could probably find someone out there desperate enough to give you around $400 or so.
I concur with @QuintupleSovereign. His estimate seems quite reasonable considering the quality and completeness of your set. Moreover, a sold eBay listing from early April with fewer coins sold for $244.53 not accounting for fees and shipping costs. However, if you had the 1935 Waitangi Crown you'd be looking at a $4,000 to $5,000 set. https://www.ebay.com/itm/New-Zealand-Dansco-type-coins-with-1-5-10-Commems-NO-RESERVE-starts-at-99-/164139815664?hash=item26377ed2f0:g:TFAAAOSw~QtefP45&nma=true&si=zwFamABP25mL9lHfud9BbcaDiM8%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557
Most of the coins are common but the first type (1936 and before) can be decent in gem grades. That's where most of your value lies. Do you have better pictures of all the coins pre 1936?
