I modified your question because coins are struck or minted rather than "printed", which refers to books and banknotes.
It's not possible to say exactly what happened without looking at your coin but my first guess is that it was exposed to some corrosive or acidic liquid. Because of the way copper "flows" when a coin is struck, the design will still appear clearly even when much of the metal has been dissolved.
Unfortunately that makes it a damaged coin with no extra numismatic value. It's still an interesting curiosity, though.
Matte or matt proof coins normally are associated with very well struck up coins with a dark or dull patina. They are normally struck in the Coronation Year of any king or queen. For example the 1902 Edward VII British Halfcrown was struck as a matt proof as well as the normal 'currency' coin. The matt proof example is worth £200 in mint condition (most are).

Assuming you mean a quarter that is normally struck, but is missing the outer silvery-colored layer ... If it is a state quarter, these have been selling in the $300-$400 range. If it is an older quarter, these have been selling for about $50
Assuming it's the same thickness as a normal dime, you have what's called a "flan". This error occurs when a coin blank accidentally slips into the bin with coins that have already been struck. If your flan has a smooth edge, it's worth about $1. If it has upturned edges like a regular coin but no design, it's worth about $2.
It's difficult to tell without seeing the coin in person. A thin strike(*) could be the result of being struck on a thinner-than-normal blank (called a planchet) or the coin could have been dipped in acid. The first would be considered a mint error and would definitely be worth a premium. The second would be a damaged coin worth 1 cent. (*) I reworded your question slightly since the process of making coins is called striking rather than stamping.
A proof coin, regardless of denomination, is a coin made for collectors. Proofs are struck from specially-polished blanks using extra-sharp dies, higher pressure, and a lower striking speed to produce a highly-detailed image with a mirror finish.Proofs are normally sold in special packaging to protect them from fingerprints and other contaminants.
A well-known musical instrument somewhat resembling the harpsichord, and consisting of a series of wires of graduated length, thickness, and tension, struck by hammers moved by keys.
Yes. Outside is normally where that would happen. If you are inside, your house protects you from any direct lightning strike.
dont know
Lincoln cents were struck on zinc coated steel planchets in 1943 only, the color often appears to be silver.

Anything that absorbs all the visible light that strikes it appears totally black.
when you request something or click on a link in mafia wars , the rovelver appears , if it last for more than 20 seconds , it mean your page struck on the request and you can fix the struck by clicking on refresh button . it will simply refresh your page :)
Answer on the back witch is tails its perpendiculreCould you provide a more complete description? There are many types of double striking* - die doubling, inverted double striking, etc. (*) Note that coins are normally said to be struck, not stamped.
Any coin of the realm struck during WILLIAM IV's reign between 1830 and 1837 normally on the 'head' side or obverse.
Please check your coin again. The phrase "200 Years of Freedom" appears on HALF dollars struck during 1975-76 in celebration of the Bicentennial.
All error coins need to be seen. Take it to a coin dealer or collector. If the weight, thickness and diameter are all correct, you may have something of value. But it likely has been altered after it was struck.
You will have to take it to someone to be seen. Value if any, depends on the cause of this error. It may be a "Striking" error or a altered coin.
