Actually, you AND the coin are travelling at the same velocity as the plane. Therefore, when you flip it up it will come straight back to you and not into the guy behind you...as long as your throw is straight up in the air, of course. This is called relative velocity: the coin is traveling at a horizontal velocity of zero RELATIVE TO THE PLANE, but it is travelling at 400km/h (or whatever the plane is travelling at) RELATIVE TO THE GROUND.
You don't. Cleaning coins destroys any value they have and takes what could be a coin worth a few cents back down to face value. Never, ever, ever clean coins unless you want to completely destroy their value.
How much is the coin worth
The price for a Sunoco Millennium Coin in the series can vary depending on its condition, rarity, and demand among collectors. It is recommended to check online auction sites, specialty coin shops, or collector forums to get an idea of what they are currently selling for.
Yes and no. It really just depends on the coin and the method of mounting. If you have something in mint state, yes, mounting it is going to severely damage the value of the coin. If it is something like a well-worn Barber Half dollar and only worth its silver content, then no, it isn't going to impact the value at all. If you are soldering the coin in the bezel, that will damage the value of the coin a lot more than just one with clips that hold the coin into place.
The metal disc used to make a coin is called a "coin blank" or, more formally, a "planchet." They also used to be called "flans," but that term is no longer as widely used.
Nothing unusual IF the airplane is flying level and at a constant speed. The coin will go up, flip, and come down as expected. However, if the airplane is accelerating...in ANY direction, the path of the coin will appear to be altered once it is in the air. For instance if the plane dives as the coin is thrown, the coin will appear to accelerate in the Upward direction.

Simply hide the coin under your thumb skin in your palm then place your hand behind the persons ear. Ta-da!

There is no official "five bob coin" in Kenya's currency. The smallest coin denomination is the one-shilling coin. It's possible that a five-bob coin may exist as a novelty item or souvenir, but it is not recognized as legal tender in Kenya.
They re-sell them (they only pay you a fraction of the value.)
See the Related Link below for a description of the coin's design.
You pay with a coin, and then Charon the ferryman, takes you across the river styx.
All grading takes into account the strength of the strike, the amount of wear on the coin and damage to the coin such as nicks and scratches.
When the Earth is traveling, everything on the Earth is traveling with it, in the same frame of reference. For example, when you are in a car or an airplane and you flip a coin in the air, the coin doesn't shoot backwards. Or, notice that when you jump upwards that the Earth didn't move from under you when you jumped.
No, however; during WW-II, some pilots carried a voluntary coin called a, 'Challenge Coin', which would help Identify the Airmen behind enemy lines.
