There aren't any really to find every one knows where they are.
US Servicemen are still missing in action (unaccounted for).
Means unaccounted for, or on the loose: The killer is still at large.
bodies are still washing up onshore so the number is still increasing
Yes even with the few minor scratches you can still sell them but they wont be worth as much as a perfect silver coin
Haiti earthquake killed 300 people and 20 are still missing . About 200,000 dead, many thousands still unaccounted for. Most buildings in the capital city damaged or destroyed, hundreds of thousands now living under plastic sheets etc.
When it comes to the U.S. cent, they are all collectible. Coin collectors have uncirculated coins from the present back over 20, or 30, or 40 or even 50 years. And more. The farther back you look, the more difficult it is to find an uncirculated coin, but there are still some around. The point is that collections of the U.S. cent are incomplete without a coin from each year and from each mint that struck them in that year. The values of the coins vary as the rarity and condition. Also, collectible coins are a volatile commodity, and prices rise and fall.
The coin is still legal tender, but If you mean get more than face value, no. Banks do not "cash in" collectible coins or paper money.
It's still 25 cents. Missing letters & numbers on coins is a very common occurrence caused by grease and dirt that fills in the dies.
American Buffalo gold coins are no longer in circulation. However, they are available at coin dealers. They are made out of pure 24-karat gold, so they are not cheap to obtain.
A total of 4,526 US personnel were POW/MIA in WWI. There are still more than 3,000 missing and unaccounted for. The remains of one Marine were identified and returned to the US and buried in Arlington Cemetery in June 2010, 92 years after he was killed.
I have seen these coins dated from 1971 to 1993, all have been gold plated and counter stamped 1960 / 1980 and are sold as "collectible" coins celebrating the 20th Anniversary of the election of JFK to the presidency. They are sold by the "Collectors Society of America" and have NO COLLECTIBLE VALUE at all. If you rub or scratch the coin, the gold well come off but it's still worth 50 cents.
Assuming the coin is circulated, and still in collectible condition, the 1865 Two-Cent Piece (1864-1872) is the second highest mintage of this short lived series of coins. Retail values as of 8-29-11 are $15.00-$30.00 for coins in average circulated condition. Better grade circulated coins are $40.00-$95.00.
