oops, you were right! I don't know what I was thinking
Lincoln is on the penny, Jefferson is on the nickel, Roosevelt is on the dime, Washington is on the quarter, and Kennedy is on the half dollar.
1 Lincolns = $.01
2 Jeffersons = .10
3 Roosevelts = .30
4 Washingtons = 1.00
5 Kennedys = 2.50

Total = $3.91
