Face value only. US nickels were never made of pure copper so your coin is either plated or has changed color due to exposure to heat or chemicals. In either case it's a damaged coin of no interest to a collector.
Cents made after mid-1982 are mostly zinc so they have essentially no copper value. Lincoln cents made up to mid-1982 (except of course for 1943 steel cents) are bronze which is 95% copper plus tin and/or zinc. They contain about 3 grams of pure copper which is worth a bit less than 3 cents as of the prices in 2011. However older cents may be worth much more as collectors' items, and in any case it's illegal to melt pennies. This, however, does not stop people from selling them in hopes that the melt ban will be lifted, however, finding a buyer for copper pennies is tough but not impossible.
There can't be a pure silver 1965 dollar. No silver dollars were minted after 1935, and in any case pure silver is too soft for circulating coins. They all contained at least 10% copper.
Cartridge cases were used for 1 cent coins from 1944 through 1946 only. 1943 1 cent coins were zinc coated steel and have average values of 5 to 25 cents depending on condition.
A 1943 Copper penny can be worth well over $100,000. They are unbelievably rare and very few passed inspection. In order to tell if it is actual copper, put a magnet to it, if it sticks, it is not copper and worth only $2.00.More, and correctionIt's likely that the coin is black because the zinc coating that protected the underlying steel has oxidized over the last 70 years. In that case your coin has value pretty much only as a memento, maybe 50¢ or so. As for the chance that it's copper, no additional 1943 copper cents have been found in over 2 decades so it's extremely unlikely to be one of those rarities. As the previous poster noted, use the magnet test to verify.
This error is the "flip side" of the more famous 1943 copper cent. If genuine, such a coin might retail in the $4000 to $5000 range. In any case it would have to be authenticated by at least one major numismatic service.
$500 with a hard shell case.
Pennies are made with a copper shell because copper is a durable and corrosion-resistant material that helps protect the coins from wear and tear. Additionally, copper is a cost-effective material for producing coins in large quantities.
Copper has one valence electron because it belongs to Group 11 of the periodic table, also known as the transition metals group. Transition metals tend to have one or two valence electrons, and in the case of copper, it has a single electron in its outermost shell, giving it a valency of +1 in most chemical reactions.

Shell case pennies are almost identical to regular pennies but contain less zinc. The only two ways to identify the shell case penny and first is to weight them in reference to a normal penny which will be a little lighter because of the higher zinc content. They will also have a much browner tone not reddish. There is no real difference in value just interesting.
You're almost certainly thinking of the cents minted from 1944-46 called "shell case" cents. They were struck from ammunition shell casings (not bullets) that were recovered after the shells they contained were fired in combat. And that was WW2, not Vietnam, of course.
Depending on the condition and whether or not it has its hard shell case, somewhere in the area of $45.00 - $200.00. I know that is a broad range but case and condition are very important.

a soft shell acoustic guitar case ranges from $20 and up. (depending on the quality.)
The n value for the 6g sublevel is 6. The principal quantum number (n) represents the energy level or shell in the electron configuration. In this case, the electron is in the 6th energy level.
