Canadian Silver

My buddy convinced me to post this just because it was so unusual. Was out this last week curbstripping in the Seattle/Tacoma area. Got a permission at an 1890's vintage house. There were a lot of wheat cents, one of them being a very toasty 1913S, and my buddy picked up a couple Indians. Down near the sidewalk I got a decent 27-28 signal on my NOX. Only 4-6 inches deep, but the ground in this area was unusual with lots of pebble and cobble mixed in so many of the older coins were unexpectedly shallow. Popped out the plug and saw the unmistakable silver rim. Thought at first it might be a Merc, but looking closer at the bust on the front of the coin it was obvious that it wasn't a U.S. coin because it was the profile of Queen Victoria. After getting it home and cleaning off the mud I was able to get a look at the back of the coin, and was surprised to see the date 1870. So, this was a Canadian 1870 Queen Victoria era 10 Cent piece. It's not uncommon to recover Canadian coins in this area, and I have actually found 3 other Canadian silver coins in the past, but this one was a real surprise. This is the second oldest coin I have ever found with the oldest being an 1864 Danish 10 Ore coin. I also happened to find a 1945 GW in the same area. Have to get back to that area after my hand heals up from a bit of surgery!! GL & HH to everyone.
