Double Nickle 55yr

My husband will be turning 55 this year.  We are going to be hosting a surprise Double Nickel party.  The guests will be invited using a card with double nickels printed on them.  Each guest will be asked to bring in their own set of double nickels to toss into the "wishing well".  For every set of double nickels, the guest gets to tell about a story about my husband.  We will be serving cake, finger foods, munchies and punch.
