Dark colored dimes and other coins are very common and have no added value.
The penny is made of copper, which gives it its distinctive reddish-brown color, whereas other coins are made of different metals like nickel, zinc, and copper-plated zinc. Over time, the penny's color may change due to oxidation and wear.
Orange-browny yellow. Hard to tell; looks like a combination of warm colours.
Yellowish Green looks like neon green color with out the neon glow. Sort of pastel.
Soda contains acids that can corrode the surface of a penny, removing the protective copper oxide layer and causing it to tarnish or even dissolve over time. This reaction is due to the acidic nature of the soda and the chemical makeup of the penny.
Mixing indigo and red will likely result in a dark purple or burgundy color. The specific shade will depend on the ratio of each color used in the mix.
Chances are, if it is the same size or looks like a dime, it may be counterfeit.
Nope. You have a novelty item made by cutting apart a penny and a dime, then hollowing out the back of the penny and popping the dime-half into it like the lid on a sandwich box.
1. Coins are struck, not printed. Paper money is printed. 2. There is no such coin as a "dime penny". There are dimes and there are pennies. That done, if your "coin" has one side that looks like a dime and one that looks like a penny, it's a novelty item made by cutting apart 2 coins, swapping sides, and joining the 2 halves. It's worth the same as all those double-head and double-tail novelty coins that occasionally slip into circulation - a few bucks at a hobby or magic shop, but no interest to coin collectors.
The dime couldn't have been printed as a penny. Different productions and not connected during the minting process. Sounds like your coin is a damaged one.
Some cents tone to a color that looks like gold but the US has never made a gold one cent coin. It's a penny.
first of all i dont know second, i want to ask this question: How would you know it is a 1920 mercury dime if the obverse was a penny? It sounds like you have a magician's coin made by cutting apart both a dime and a penny, and hollowing out one side of the penny so the dime side snaps into the penny side. It's interesting but has no value to a coin collector.
.10-that would be like a dime compared to a penny.

See this page: http://cointrackers.com/coins/148/1945-mercury-dime/ for what the 1945 "mercury" or "winged liberty" dime looks like.
It looks exactly the same as the 2010 or 2012 penny.
The US coin looks very much like a modern US penny
It looks like it HAS been rounded to the nearest penny.
