A pennyweight (abbreviated dwt) is a unit of mass that is equal to 24 grains, 1â20 of a troy ounce, 1â240 of a troy pound, approximately 0.054857 avoirdupois ounce and exactly 1.55517384 grams.
This forces the very edges of the penny to push up which is what gives the penny the lip that it has. The size of the penny is very important. The weight of it is 2.500 grams exactly. The diameter is 0.750 inches or 19.05 mm. Finally, the thickness is 1.55 mm. The good thing about coins is that their sizes are always the same for the most part.
