The kind of interesting thing about this coin is that in a way it is a precursor to the 20p, being of the same nominal valuation in relation to the £.

It was referred to as the "Barmaid's ruin" when it was issued because it was commonly mistaken for a Crown coin in dimly lit situations, resulting in a shillings loss for the recipient, about the equivalent of a present day £1 coin.

Another great Victorian coin
