I've had 100-silver-coin weeks and 10-silver-coin years. No biggie. But you gotta go out and hit every target of opportunity that comes along if you're chasing silver.
Once you pull that silver from the ground, it's not gonna be there ever again.
People have been pulling silver from the ground for hundreds or thousands of years, it's been made much easier in the last 50 years or so. People have stopped dropping silver into the ground in the most common way of years past, by losing change.
Thankfully, there were special members of society in these interim years between the development of modern metal detectors and their future variants. People who knew that the only way to preserve the bulk of ground-bourne silver coinage was to mask it with screw caps, pull tabs, bottle caps and canslaw.
God Bless the nail makers, they have saved many a coin from being sought out in these intervening years and given rise to the need for newer, more advanced metal detectors. Technology marches on because of these people, the many who shared a Coke and a smile, the Pepsi Generation, MGD and King Cobra lovers alike.
One day you too will pull an Old Style can or some large part of one out of the ground and after rechecking the hole, recognize it for what it is, a silver-coin preservative.
