4 dirty old pennies on a keyring. Each pne had a significant date. 1988 for the year he was born. 1990 for the year i was born. 2010 for the year we met and became a couple. 2012 for the year we got married. I got so teary eyed when i realized the significance of this. I tied it into my bouquet and walked down the aisle with them close to me.
