All I know is that the probability of you getting any serious answers is pretty low.
Also, wouldn't it land on the penny side down almost all the time because the penny is heavier?

I'll take a stab at it:
The answer is infinity. Even after a million flips there is still a chance that you could change the the total by more than 3%, albeit, extremely unlikely. Possibly you are wondering within a confidence of 99.99%, however the answer to the question you have stated is infinity.

Sounds like you'll wager on anything. Therefore, I question your username...

and it would always stay within 1% of that no matter how many more times you flipped it.

? The heck?
If we have 500 000 heads and 500 000 tails to start, it would only take 20408 more flips of one side only to change the value from 50% to 51% (.5 + x = .51(1+x), x in millions of flips).

Now, if you were to glue together a Dime and a Penny and you flipped it 1 million times you would have an accurate answer as to how likely it is to land Penny side up versus Dime side up. My question is, what is the MINIMUM number of flips you could give it without the percentage ever changing again more than 3% either way?
I have no idea what the answer is by the way.

This is just a Bernoulli probability, isn't it?
P(k) = nCk * p^k * (1-p)^(n-k) = 3%
where p = probability of Penny side up, which you can't really determine without knowing how the penny/dime is weighted.
Solve for k
i think ???
(I just googled up, apparently a dime and penny both weigh 2.5g. But I guess you were asking for a weighted example.)
