Divide your youth group into teams. About one or two months before the funds are needed, give each youth member something to put coins in (e.g., jars, piggybanks, plastic containers, etc.). Each team member tries to collect as much change as possible from friends, family, etc. We had 20 youth participating in this fundraiser and raised over $300! The winning team were treated to a nice dinner and night out with the youth leaders! Easy and inexpensive, but brings great returns!
