You do realize that unless you were in near-Earth orbit, that the
combined mass of 10 pennies is insufficent to influence the mass of an 11th
penny at even a millimeter distance. If you have a table to have the
pennies land on, the table's mass will cause much more influence than the
mere mass of 10 pennies. Even the local air above the table has enough of a
gravity influence to be about the mass of 1/100th of a penny.
In short, you are ignoring the local matter of a tiny zone of gravity
influence and focusing solely on the mass of 10 coins.
Now if each coin was made of something far more massive than the local
air mass + the mass of the table itself, the experiment "might" have a
meager level of scientific value. The problem is that if there is a vein of
gold 100 feet off to the side of your house, the mass of a gold vein would
have dramatically more gravity attraction than 10 coins made of plutonium
influencing another plutonium coin. In short, your experiment is pointless
unless you can conclusively isolate your experiment materials from the local
gravity of the Earth by means of mathmatics or physically. The gravity of
your own body is more massive than 10 standard pennies and usually less than
the table (unless it's an inexpensive folding table).
That, of course, doesn't even factor the frictional quality of the
surface of the table, and oil from your fingers influencing the air friction
factor as the coins are flipped. Pennies look identical, but are not
entirely identical in manufacture if you look at them with a microscope. So
it is not akin to having 10 perfectly duplicate pennies mucking about with
an 11th duplicate penny.
Seriously, are you really considering the large number of subtle factors
in your experiment that will influence it far more dramatically than the
immediate mostly lesser mass than everything near it?
But, hey, do whatever you want. Just don't expect a serious scientist
to even consider your results with such a sloppy uncontrolled experiment
which cannot be duplicated accurately anywhere else in the world.
