Thoroughly mix sugar, coconut, pecans, vanilla, graham craker crumbs, peanut butter and melted butter. Use a heavy wooden spoon or your hands if necessary.
Chill mixture before rolling into bite-sized balls. Melt the parafin and chocolate chips over very low heat.
Using a toothpick, dip each ball into chocolate mixture to coat. Cool on waxed paper. Use a small spoon to fill the toothpick hole if necessary. Store in a closed container in a cool place. Keeps for several weeks.
