For current US coins: Cents and nickels have smooth edges.Dimes, quarters, and halves are reededDollars have "lettered" edges which are smooth but include things like mottoes, the date and mint mark, etc.Reeding was originally used to make it easier to detect removal of metal from a coin's edge. Criminals would take a small bit from each coin; added together it amounted to a lot of stolen gold or silver.Reeding on US and Canadian coins continues today as a matter of tradition.
