Thanks Wayne1956!! I think my roll searching will end as well after this attempt. I used to watch a few vids from a guy named "Silverpicker" until they got too long and then he started making much bigger buys than I'll ever be able to do. But when he first started out, he would just flat out ask people having rummage sales if they had any coin collections and then start negotiating there if they produced some. He was from some much larger northern metro like out of Mich. or upstate NY because he was when a day trip of the CAN border.

LoganRyche- sites like Coin Tracker will give detailed accounts of what typical North American silver coins are worth. Beyond CAN and Mex you'd have to do more digging but can probably find at least what amount of silver was in a coin. Good luck!!
