ARNPRIOR 1952 Canada Silver Dollar : eBay Guides

My 1952 ARNPRIOR has two full water line. There is no trace of the bottom water line. The second water line is almost erased.

Is this really the ARNPRIOR for the 1952 ? knowing that the reverse was modified in 1952, because the image of the canoe on the coin had a larger islet tip at the right end compare to the 1950 & 1951.
