Anyone these days making a 2X2 (or whatever) size snap-together capsule with some kind of adjustable or otherwise modular cushion to hold odd sized coins? Say, old tokens or ancients?
I see what you're asking. No i don't believe there is anything for weird sized or oblong coins that i know of. Seems you have to get kind of creative. Personally, i use envelopes for my ancients, and dollar sized air tites for my off center wheats. I have tried modifying world premier coin slabs for both but it can be difficult.
Hmm... they offer those foam rings 1mm at a time so that's probably the answer. Anyone offer the same thing only in a square (not round) case?
If you don't mind the occasional rattler, you can use the Lighthouse Quadrum holders. I believe they range from 14-41mm by 1mm increments. If you need a 13mm, you can get an air-tite A-13 ring and put it into a Quadrum Half Dollar holder.
My collection is heavy on world coins, and I've never failed to get an exact fit with Air-Tites. Not aware of anyone who does the same concept in a square format. Edit: I wasn't familiar with the square Lighthouse holders NPCoins linked to.
Yes, they've been around for many years. https://www.amosadvantage.com/coin-guides/coin-world-coin-holders
The quadrum 50x50 capsules also come with a uncut foam insert so you can cut it for odd size or shaped coins
Guard House Tetra sounds like what you're looking for - they're all 2x2, but come with various sized cutouts in foam inserts - you could probably buy a smaller size (dime, cent) and cut the hole to size for your particular coin, or just adapt one of the larger sizes. http://www.jpscorner.com/guardhouse-coin-holders.html
Lighthouse makes a large capsule that includes black rings sizes 21-62mm. Available from many sources, like this: https://www.amazon.com/Lighthouse-2...0198RY0DI/ref=cm_cr_arp_d_product_top?ie=UTF8
