I would imagine it depends on the angle, height, rotation and where you catch it, or if you let it drop to the floor. Assuming consistency, it's reasonable to assume that one is indeed more likely than the other, but I don't see how we know which one until we have a sample.

Assume heads starts down. Then in order, the side that's up once we flip is

heads, tails, heads, tails, heads, tails.....

So at any point in time, heads is up >= 50% of the time. The fewer times it flips, the higher the edge. You can probably find experiments for this kind of thing in Google.

That actually makes sense.
