I am not sure but I think these are Irish ? wts used to measure against gold,silver or coins. I have heard that they were used in trade to assure proper weight of coins but would be grateful if someone could steer me in the right direction to find out more. They were discovered under the floor boards of a fallen in log cabin on the edge of Georgian Bay. They were inside the deerskin bag in the pictures. Found about 40 years ago Any help would be appreciated.
