If you are seriously interested in maintaining the value of your coin collection, consideration of how they are to be kept/stored is paramount. Ideally the storage system should be decided on before you start collecting but in fact the reverse order is the more usual.
Coin albums are a reasonably priced way of keeping your coins - and have the great advantage that the coins are easily seen/presented. The albums are often in the form of "ring-binders". Pre printed sheets giving information about the various coins are normally available. Being able to see the coins from both sides also means they need not be taken out to be viewed from both sides and the less handling the coins are subjected to, the better.
Ideally the storage system should fulfil the following criteria:
Apart from the actual container in which the coins are kept, thought should also be given to the location.
A place of low humidity are relatively constant temperature is therefore preferable - so attic and basement are not desireable. As however, most collectors enjoy viewing their collection quite often these two locations are unlikely to be selected.
Previously it was not uncommon for plastic coin containers to contain PVC, a chemical which ultimately, over time,could damage the coins. This is almost cetainly not the case with any containers bought from reputable manufacturers nowadays - it is, however, a point to consider if buying a second hand container over ebay or on a flea market for example.
