Nosing around again at the dig at Market Square today, as the Tonka trucks roared, I was interested to see the coin of the archaeologists had uncovered, a 1812 half penny token. My shot of the side with the king's head is not that sharp but it does confirm there are no words on that side.

Let's see what Lord Goog may know - looks like one of these - a "Tiffin" half penny issued by a Montreal grocer by that name. Given that green line of the oxidization I'd bet it is from the 1832 copper rather than the 1837 brass stamping.

Also, in the red square at the dig you see a corner of an arch sticking out. That is the mirror of the still existing 1841 arch found a few feet away in the stil used section of the Market Square wing. The arches are apparently exactly ten feet apart and the pattern continues out into the destroyed portion now being uncovered. The photo with the blue tarps shows the back soot from the 1865 fire that brought the walls all down.
