I am struggling to find something suitable to present them in. Obviously need something with 30 or more holders, although size could be an issue as the Kooks i have are in different containers, I'll have to get exact measurements. Will I need something custom made? lol
Presentation cases that hold 2x2s may work for you. There are a lot of different kinds out there. Here is an example.... http://www.wizardcoinsupply.com/nova-exquisite-wood-stackable-coin-drawer-for-2x2s.html
Does the series have a specified end date? if not why would you want one as you're just going to need a bigger one each year!
I found a partial solution to the display conundrum..partial because mine only holds 24 rounds I put them in Black ring Airtite capsules and used the Airtite Album to house them in.These are available on ebay ,but I purchased direct from the company website.Album has 6 pages with 4 rounds per page ,giving me 24 places. After 2013,I will be starting another Can post a pic of the package if you are really interested.Whole set up cost about $80.00 AU ,inc shipping.
Bought a couple of display boxs of this guy. http://stores.ebay.com.au/coinsmedalsandgifts Great quality product and he custome makes so you could send him some specs with for a quote. Might be a bit pricey but it was just a thought.
