Off the coins, and off our aircraft carriers.
The first politician to be on a coin was in 1909, 116 years after the first American coins. Second was in 1932, third in 1938, fourth in 1946, and fifth in 1964.
The duration of these coins has been very unusual - the cent hasn't changed in 114 years, the quarter in 91 years, the nickel in 85 years, the dime in 77 years, and the half dollar in 59 years. Such longevity in coin designs is unusual for the period 1793-1932, and it would be good to get all the politicians off the coinage and get back to Lady Liberty or historical figures.
I'd like to go to an Oldies But Goodies design.
For the one cent coin, assuming we really need it, go back to the Indian Head design.
For the five cent coin, assuming we really need it, go back to the Charles Barber design.
For the dime, I'm partial to the Seated Liberty design from the pre-Civil War era.
For the quarter, the Standing Liberty design had terrible relief and wore down quickly, so I'd go for the Barber design.
If he need a one dollar coin, I have no problem with the Sacajawea design.
