Found Ten Canadian Dimes In The Customer-Wrapped Rolls - And Then A Mercury Dime

I acquired 15 customer-wrapped dime rolls on Friday while visiting Cape Cod. Soon a Canadian dime popped up -- which I replaced with a US dime (as I always do) because I plan to spend that dime when my wife and I visit Montreal later this year. When two more Canadian times showed up in the next roll, I began to get suspicious: i.e., someone who recently returned from there had slipped those coins into the rolls. Sure enough, I kept finding more Canadian dimes (none of which contained silver). Opening the last roll, I found the tenth Canadian dime -- and a 1927 Mercury dime that the scoundrel hadn't noticed. Karma, indeed...
