    Byzantine 40-Nummi Piece

    The 40-nummi piece was the largest and heaviest copper coin minted under Justinian. About the size of an old Canadian silver dollar, it weighs 22.76 grams. It was struck in Constantinople (now Istanbul), the capital of the Byzantine Empire and is part of the National Currency Collection, Bank of Canada.
