Value
You would have to use a half dollar coin (which is not common) along with 1 dime, 1 nickel, and 1 penny
A quarter and a nickel. It is a trick question. One is not a nickel, but the other is.
A nickel is a five-cent United States coin. A dime is a ten-cent coin. Therefore, a nickel is half of a dime.
If it is a Mint error it may be worth a few dollars, take it to a coin dealer to see if it has any value.MoreIt's called a Jefferson nickel rather than a Monticello nickel. If by "double struck" you mean that Monticello is on both sides (which would account for the lack of a date) what you have is a novelty item called a magician's coin. There's more information at the question "What is a double headed nickel worth?"
one of the coin is a nickel and one is a half dollar coin
There is only one combination of two coins that will equal 11 cents. That would be one dime and one penny. Since the question limits us by stating that one coin is not a penny, then clearly the OTHER coin *must* be a penny.
We have never heard of a 10 cent coin called a penny, but at one time there were 1 cent coins called nickels. This happened because the 1 cent coins were made as thick as a nickel.
By far it is the penny.
One coin is a quarter and the other one is a nickel. The quarter is NOT a nickel!
There's no such coin. Lincoln is on the penny.
The coin you have described sounds like a novelity coin and has no value other than the materials it is made from.
Penny, nickel, dime, quarter, half dollar, dollar.
It does not. When the price of silver and other metals went up in the 1800's, someone game up with the idea of using a nickel/copper alloy for a new coin. This new coin was the Shield Nickel and was called a nickel, well because the metal nickel being in the coin.
A nickel cigar, a ticket to the theater (nickelodeon), a ride on the trolley, a nickel Coke, a glass of beer, a piece of pie, a magazine, coin operated pianos, and many other coin-operated machines of which the nickel was king, followed a close second by the penny. The nickel even went far in penny arcades. And like today, there was always the nickel slot machines.

The reason your coin is the size and color of a nickel is that it IS a nickel, not a penny. Remember Roman numerals? V = 5. Please see the Related Question for more information.
