take 60 pennies, form the number 60 on a piece of poster paper or poster board, glue on the pennies. Have friends sign it. If having a party, have them sign it when they come. Cut the board or paper any size to fit the number 60. You could also frame it for him afterwards. for my husband's 70th party, I mentioned if they wanted to bring a small gift, not to spend over 70 cents on it! This was quite a hit at the party! People had fun figuring out something for the price & he got a kick opening the gift up!
