Not unfortunate at all ! Canada has created some very beautiful coins - I'd much rather have found your Canadian silver dime ,than our Rosie of the same period . Nice find ! Welcome to Treasurenet !
First silver coin is special, no matter what it is or where it's from. I still have my first, a 1961-D Rosie found in 1991. You'll always remember that first one- Congrats and here's to many more for you!
