I like the air tight capsules especially for gold even if it cost a little more, I like to play with my collectible coins sometimes so having them stored individually, I don't have to worry about gloves, body oils and oxygen...whatever else ever. I like to collect different designs rather than get one large tube of one thing. If I do then I just leave them in the tube un-opened. Not a fan of the cheap cardboard holders thingy unless it's for old coinage that already has some wear, they can still get beat up in storage. I never sold any so I don't know if it makes a difference on the resale market, I tend to prefer like new looking coins.
