Although no coins were thrown at my daughter's 21st century southern wedding such a custom is known in the south, albeit mostly in Victorian times.The poor must have appreciated that.
It was a popular custom in Scotland and designed to bring luck and prosperity to the married couple. As for North Eastern weddings I can recall the chucking of coins outside Saint Luke's and the laughter and scramble that took place as a result.
Hopefully others will know more and share their knowledge.
