It'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?"
This is not a Mint error coin. It has likely been altered by placing the nickel and dime in a vise and squeezing them together causing a reverse image of the dime to appear on the nickel. The coin has no numismatic collectible value.
Chances are it is worth something. The question though is, was it a nickel struck on a quarter blank? Or was the nickel simply struck off-center? If it was struck on a quarter blank, the edge will have both redish brown and white. If it was struck on a nickel blank it will be a solid color. The best thing to do is take it in to several coin shops and get different opinions on what its worth. It is hard to give values for error coins sight unseen. But some coin dealers specialize in errors while others use them simply for curiosities.
The melt value of something is the value of the metal itself. For example, a 1964 nickel has a melt value of 5 cents because 1.8 cents worth of nickel and 2.7 cents of copper.
All 2003 US nickels carry the standard portrait of Thomas Jefferson on the front and an image of his home, Monticello, on the back. None are special and none have any extra value in circulated condition. 2004 and 2005 nickels carry different designs in honor of the Lewis and Clark bicentennial, but again any that you find in change have no extra worth.

There was no "victory nickel" struck in the US. There was, however a Canadian Victory Nickel, and there were US nickels struck with 35% silver (from 1942-1945 with a large mintmark on the reverse above the Monticello) and those are worth $1.50 or so.MoreIf your nickel is a US coin dated 1883 to 1912 with a picture of Miss Liberty on the front, please look up the Roman numeral for "five". It's the letter V, and is the coin's denomination.

US nickels show a picture of Thomas Jefferson's home, Monticello, but they're not minted there. At that time there were 3 active mints: Philadelphia (no mint mark), Denver ("D"), and San Francisco ("S") although 1950 nickels weren't minted at the latter. Please see the question "What is the value of a 1950 US nickel?" for more information.
That depends on which version you have. If there is no mintmark, then it's made of copper and nickel, worth maybe 50 cents in decent condition. If there is a large letter P on the back (above Monticello), then it's a silver war nickel, worth a dollar or two.
The US nickel was first issued in 1866. Please double-check your coin.
