There's only one Lucky Loonie and it's in the Hockey Hall of Fame. I've seen it. What you have is $25 Canadian Dollars. It's worth CAN$25.
I have a Canadian 50 cent coin. Rare? Yes. Worth more than 50c? No. I also have a first pressing Loonie (they're not the shiny ones you see, these are both shiny but the design is frosted, they look much better than the shiny new ones) it's worth precisely CAN$1.
^^Nah, some of the coins you have might be worth more than $1 or $0.50. They may be worth $1.03 and $0.52 now.
My mum has uncut sheets of the old $1 bills, $2 bills, $5 bills, and I think even the $10 and $20 bills. They were either replaced or completely discontinued (ie: the $1 and $2 paper bills). Every sheet has 40 bills on it, so what started out as a cheap hobby ended up being very expensive when they recently replaced the $10 and $20 bills.
They're also cost more to purchase when uncut, so 40 x $20 notes doesn't mean that sheet cost $800.
