Having a silver coin collection is an advantage in many ways.
It provides a future asset that grows. It provides interest as the beauty and aesthetic presentation of many coins is truly appealing. It is also educative since, as there is much history connected to many coins and how they are produced and why, one tends to want to know about the coins and their place in history.
Some collectors collect only one type of silver coin, perhaps all American or all Canadian coins. Some collect a particular type. Silver dollars or Pandas. Other collect proof coins only. Proof coins are those that have been specially struck for collectors or as presentation gifts for VIPs or to commemorate a particular occasion or person in history.
Some collect only rare or old coins. Usually that requires a degree of wealth. Many rare coins can be worth thousands, even millions in some rare cases.
Some collectors are interested in the monetary value only with little regard for the aesthetic appeal, and so collect only coins that they consider will improve in value over time.
There is such a diverse range of silver coins that one can collect almost anything.
Probably it is, at least initially, a matter of taste after first noticing all those nice shinny things!
Whatever the reason and what ever coins one collects, having a silver coin collection is sure to give immense pleasure one way or another as well as give some additional security for the future.
