[Batman] What would happen if Batman swapped Two-Face's coin with one that always landed on its non-scarred side?

In Batman the animated series, Batman once swapped Harvey's coin with a trick coin that always landed on the edge and Harvey nearly ran off the side of a building flipping the coin again and again.

But what would happen instead if Batman swapped Two-Face's coin with a trick coin that was weighted towards the non-scarred side? Would Two-Face eventually catch on to the trick or just believe it to be random chance each time?

First, let's realize that Dent is kind of fixing the results anyway.  For example, in Nolan's The Dark Knight when he is in the car with Maroni, he flipped a coin.  It spared Maroni's life.   But, in a "do-over", he flips it again and gets the result he wants, but excuses it that it's for the driver, so kills him, resulting in the car crash.  -- So even without a fixed coin, he strives to get the result he ultimately wants. That said...

Dent isnt stupid.  Even he would know that the coin cant land on the same side 100% of the time if it isnt fixed.   Eventually he'd figure it out.  But for the sake of argument, let's assume he doesn't and continues to believe it to be still random, just extremely coincidental... he'll eventually re-fix the process in his favor.

For example. --- if you flip a coin, catch it in the palm one hand then flip and slap it on the back of your other hand, you're in essence changing the flip of the coin from the way it landed in your first hand.

So, he would then just orchestrate the toss and the catch and (depending on how it's fixed) either flip it onto his backhand, or not -- however he decides to achieve whichever outcome he actually prefers.

If it landing in his palm results in non-scarred side up, and he wants the scarred side, he can slap it onto his backhand (flipping it to the scarred side.  -- or if it was fixed to land in his palm scarred side up (so that flipping it would result in the non-scarred side up) then he can just chose to not flip it and let it rest as it landed in his palm.

Either way, the outcome is rigged by his choice versus the coin's land.
