Daniel, I guess the easiest way to get silver coins would be to go to the mint website and order them, they will magically appear on your door step in a bout 10 days. If by the term "easily" you actually mean at little to no cost, then you are using the wrong term.
You can either get easy or cheap, not both, otherwise everyone would have stacks and stacks of silver.
Coin roll hunting for silver is not a simple 15 minute get rich scheme. Most people who post on here who have any measure of success (over time) get 1 silver dime per box ($250) and about the same for half dollars. This ratio is achieved by VOLUME, many, many boxes a week, over years.
