The picture leaves a little to be desired, but it is a 1986 British nickel/brass Two Pound coin commemorating the XIII Commonwealth Games in Scotland.
In uncirculated mint condition, it might get £5 GBP.
The same coin was also issued as a Proof FDC coin in silver and gold, but that would be reflected in the asking price.
So the penny is history but I am wondering how is it cheaper to use the nickel 5 cent piece?

You did not tell us who made it or what type of firearm it is.
See whether that object can attract nickel,steel,and metal.
It's worth five cents. Gold plating doesn't add any value.
Totally rare, i.e. it can't exist. Every nickel must have two sides, whether or not either side has anything printed on it.
Face value only, regardless of whether it's from the US or Canada.
It depends on whether it's made of standard copper-nickel alloy, or is one of the part-silver "war nickels" minted when nickel metal was needed for the war effort. Please see the Related Question for details.
A United States 190 Liberty Head V Nickel is worth between $250 and $135. The spread in price range depends on the condition of the coin and whether or not it is registered.
Before wondering about what it is worth, you should take it to a coin shop and see if it is a true mint error or is it a coin someone has sanded one side off.
According to this particular site the value is betwen $5 and $10. I'm in no way an authority on the issue, nor am I ovrly familiar with the site. I simply have the same coin as you and was wondering myself :)
Yes. It consists of nickel, nickel, and nickel.
