Hi John. To be honest, it doesn't matter how you store coins so long as they are not going to be physically damaged from other coins (so a jam jar is not ideal!), they are dry and not exposed to noxious chemicals (some of the older pvc plastic envelopes can degrade, but modern ones should be safe). These steps ensure, as far as is possible, the coin will not change too much in appearance from when you get it. Capsules are quite popular as they allow you to look at the coin without touching it. But some people use acid-free paper envelopes as an alternative. I and some others here use traditional coin cabinets. They are made from seasoned wood (usually mahogany) and the coins are stored in recesses in trays. Which if you have any coins old enough to have belonged to a collector who wrote details about the coin on a 'ticket' (small paper disk) is nice, as the ticket fits under the felt cushion in the same recess as the relevant coin. Here are some of mine in their tray: You will see they they are toned (or as Americans sometimes say 'tarnished'!) so I'm not too worried about picking them up to inspect them. Perhaps if I collected modern coins, particularly proofs, or BU copper or bronze, I might be more inclined to use capsules ... Oh, and welcome to Predecimal! What sort of coins do you collect?
