Filled die errors are very common and have little value if any.
...The 1943 cent is steel, not silver. In absolutely pristine condition it can go for around 10 cents but are around 4 or 5 cents in average condition.
It depends on the error. If the coin is damaged and the 4 is missing, it takes away value of the coin. If the coin isn't damaged its possible it is a grease filled die, a minor error that adds only cents to the coin's value. If worn/damaged the coin is worth about 2-3 cents. If uncirculated the coin is worth about $2-3 with the grease filled die.
1943 steel cents are rather common and only worth a few cents usually, unless they are in incredibly great condition. In average circulated condition they are worth around 3 or 4 cents.
In average circulated condition, these are worth about 10 cents each; in pristine uncirculated condition, they can be worth up to $4 or $5. (There are still plenty of them around!)
A genuine 1943-S copper (Bronze actually) cent would have a value of $75,000.00 or more. Only 4 have been authenticated.
The missing 4 is likely due to a foreign substance in the die when the coin was struck -- not very rare. Collectors for this type of thing generally will only pay a dollar or less for it.
The 1943 steel cent can be bought in circulated condition for $2-$4 and in uncirculated condition for $5-$10.

I actually have a 1943-S steel penny without the 3. This is caused by the number being filled in with debris from the minting process and is called an "error". Errors are collectable and price varies considerably from one source to another. Although not rare I consider one to be worth $2-$5 depending upon the condition of the coin.
The silver nickels are worth about $1.50 in scrap silver if circulated or up to about $3-4 if in excellent condition. The steel penny is worth about 2-3 cents if circulated and up to a buck or two if in brilliant uncirculated.

You should probably take this to a professional coin dealer for an accurate valuation. The value would depend on the condition of the coin, the perceived cause of the error (e.g., is the "4" missing because of a die error or because someone went at it with sandpaper and ground it off the coin), the extent of the error, and how "interesting" the coin looks. A collector of error coins would probably pay at least a few dollars, but whether or not it would be worth markedly more depends on the abovementioned qualities.

None of the coins can be missing because there was not a set number of them made. The number of authenticated Bronze 1943 Lincoln cents are: Philadelphia - 10 San Francisco - 4 Denver - 1 The Denver example sold in 2010 for a little more than 1.7 Million dollars.
8d (eight penny) nails are made from 10 1/4 gauge (oh how I detest those English/American standards!) steel wire.10 1/4 gauge wire has a diameter of 0.131 inches or 3.33 millimeters (metric - I can relate to that!).
