Which two United States coins add up to a nickel?

Question

This is not a joke. These coins DO exist...

Answer 1

But do those coins exsist today?!?!?!

Answer 2

1851 Three cent piece designed as a result of the decrease in postage rates from five cents to three and to answer the need for a small-denomination

1864 Two cent piece was produced in the United States from 1864-1873 with decreasing mintages throughout that time

The silver three cent piece was discontinued by the Coinage Act of 1873.

Answer 3

I don't know the old coins but basically you can have 5 pennies (cent) to add up to a nickle plus a nickle itself is 5 cents. That's two ways of looking at it.

Answer 4

a three cent piece and a 2 cent piece
