consider this scenario (completely fiction)
It's 1900- fresh minted dime comes out in a roll, goes to bank for .10, customer gets it for .10, uses it to buy a burger. That fellow gives it as change to a kid, who spends it on a cone, then that fellow gives it as change to someone else.
Its 1910-that same dime is now in another roll and is picked up by a business. They give it as change to someone, he puts it in jar for 5 years, kid takes it out and buys another cone(different kid). That was the last sale of the day so the cone seller puts it in his spare change jar and it sits at the bottom for 10 years
its 1925- finally deposited again at bank, than rolled and stored in vault for 5 years by coincidence.
its 1930-finally opened up the roll, spent on sodas and than dropped on the ground by a careless owner. picked up a month later, than stored in a jar for 15 years
its 1945-deposited in bank, than spent on the third cone in its life(new record for a 1900 dime) that seller gives it as change to some guy who loses it on the street. somehow the luster is still there and a crow picks it up and carries it to his nest. sits in a nest for 30 years, until a logger cuts the tree down and the coin falls out onto the ground. No one notices it for another 5 years, but than a little boy picks it up and spends it on some bubble gum.
its 1980-the bubble gum seller gives it as change to a coin collector who saves it in his 2x2 until he passes away and his family trades it for face value

than the bank teller, who collects as well, finds it and adds it to his melt pile because the poor thing is in AG for being circulated that long. The dime gets sent to a refinery, and is melted down. The refinery than uses the silver to make a bullion bar, but thats another story.....
