An unsolicited arrival

In yesterday's mail, my wife received this from some charity trying with it to guilt her into making a donation. I expect they had no idea they were including a nearly eighty-year-old coin in their appeal.

The 1947 Canadian nickel still advertised the British king as Emperor of India and the mint did not receive the corrected dies until the following year. In the meantime, the mint added a tiny maple leaf to the space near the foot of the -7 in the date. So there were at least two 1947 nickels in circulation, with and without the maple leaf. This one shows, rather worn, that tiny maple leaf.
