Provident Metals has best deals that I have found. As far as best they seem to be pretty much all the same from my experience.
These are the best no doubt. And cheap in bulk. I once had a 2 oz gold kangaroo in one and accidentally dropped it on the concrete. The holder cracked but the coin was still perfect. http://www.airtiteholders.com/Categories/category.aspx?CID=1 Jim
Airtite are usually the best. What are they for and how many do you need? Seeing as you're in Aus try PB http://www.perthbullion.com/shop/search/?query=Capsule&searchbtn=Search
If anyone after Original Perth Mint capsules - Au N Ag - recent style Chip do carry the Full range. I believe these capsules are the best in the market. They have extra "rim height" around the circumference; So will stop scratches when on the flat surface. Please enquiries , availability only in the Forum for members usage. Chip provide individual private services. Look / Seek / Ask no more else where. Price a fraction more, as you pay for my services. Other services are calibrating suitable capsules for yours coins. Please be patience as I am a busy person. Can shipping Worldwide. Chip
In Australia, I don't know but if you are referring to the Ultra High Relief Elemetal silver rounds, you can check eBay for listings similar to this: 191817496941 By the way, what coin or medal is that which you have as your avatar...it looks neat. .
Thanks for this post! I see the Perth Mint sells capsules for its 10 oz Koalas. I wonder if anyone in the US sells these? I have a 2012 10 oz Koala I got recently cheap ($2.50 over per ounce) in part because the plastic case is all cracked and even missing part- coin had a couple "smudges" and what looked like part of a finger print that I got out easy so with a new holder it will be like brand new. The co. that makes Air-tites doesn't have one that fits the Koala unfortunately. Jim
Airtite don't make many Perth capsules especially the older one. I do shipping worldwide. Postage rate just don't justified. All Original from Perth Mint. Can supply Au or Ag capsules , no worries Better services than any company can provide. I am just independent member that helping in this forum.
