When the slow times come(and they will) it has always helped me to have a collection to be trying to complete as well as finding silver to keep you going. I also keep ALL high quality condition coins I find because they will always have premium value down the road. The last bit of advice, look at it as a treasure hunt, not an investment strategy and enjoy the coins you find. Study them and learn all you can about them because the more you learn, the more discriminating you will be in what you keep and what you dump and you will not pass up errors or varieties in the race for silver. Enjoy the journey as well as the destination.
