get several sheets of metal or plastic (depending on how many coins your country has). Then measure each coin in diameter and cut out holes in one sheet of metal/plastic that are smaller than the designated coin but big enough for the next biggest coin to pass through. then repeat for each coin. when you're done with the holes but the sheets in a sturdy box and attach them to the walls of the box about 1 inch appart. Then pour in the coins and shake the box. the coins should be all separated by size.

The first recorded reference to a vending machine is found in the work of "Hero of Alexandria", a first century engineer and mathematician. His machine accepted a coin and dispensed a fixed amount of holy water. http://wikipedia.org/vending_machine
A biased coin is a coin that does not have an equal probability of landing on each side when flipped. For example, it may have a higher likelihood of landing on heads than tails due to an uneven weight distribution or design. This bias can be quantified, typically expressed as a percentage, indicating the probability of each outcome (e.g., a 70% chance of heads and a 30% chance of tails). Consequently, repeated flips of a biased coin will yield outcomes that reflect this skewed probability rather than the expected 50/50 results of a fair coin.
A British 10p coin contains 75% copper and 25% nickel.
