Preheat the oven to 350 degrees.
In a large bowl, cream together the lard, sugar, and brown sugar until light and fluffy.
Mix in the eggs, peanut butter, salt, baking soda, vanilla, and flour, stirring until well-combined.
Form the dough into 1 inch balls, then roll the balls in white sugar.
Place the balls on cookie sheets, flattening slightly.
Bake until the cookies are browned at the edges, about 10-12 minutes.
