My mother (Born in Liverpool of Scottish mother) had Dad each New Year exit the rear door of our home with with a piece of coal and re-enter the front door. She said it brought luck to the home to have a dark haired man enter the home first in the new year.

When I left home, my Mum gave me a piece of coal to carry on her tradition. I have been faithful. (Although the hair is grey, now!)
To you Mum!
