Even an honest person’s consistent flick of the wrist introduces a degree of predictability. Furthermore, no coin is truly perfect.
Why Short Coin Sequences Often Aren't 50/50
The initial force and the axis of rotation are rarely perfectly random, meaning the "randomness" is often more a product of human inconsistency than true probability. Tiny imperfections in weight distribution, wear and tear from circulation, or even the specific design of the portrait can introduce a persistent, though often small, bias.
The side that was facing up at the start of the flip has a slightly higher probability—roughly 51%—of facing up when it lands.

Understanding Short Sequences and Coin Bias
The law of large numbers assures us that over thousands of tosses, the results will converge toward 50/50, but any finite sequence can appear chaotic and non-random. Ask a hundred people what the odds are for a coin landing on heads, and nearly every one will answer 50/50.
