It sounds like your best bet would be to decide what type of silver you like. That way you can enjoy this new hobby for yourself while you're still alive. Then, choose a time schedule of how often you purchase and either how much you will spend each time or what you buy each time. That way, your investment/collection will hopefully have minimal risk and will be better averaged out. For instance, suppose your collection will be government issued silver bullion. So, every two weeks you buy an ounce coin from your local coin shop. You should get lots of pleasue from collecting all sorts of coins and years. Then, by the time you croak, you have hundreds of ounces of silver to leave to someone.
