A body floats into water when it displaces a volume of liquid whose weight is equal to the submerged part. If the body weights more than the displaced volume it sinks.

according to Archimedis principle "the weight of the floaing body is equal to the weight of the water displaced by it.the ship floats because the weight of the ship is equal to the weight of the water displaced by it.but it is not in the case of a coin

Its all in the shape. The laws of bouyancy show that any object that is heavier than water (such as metal) will float, so long as the amount of water it displaces is less than its own weight. So, if you got a hammer and bashed your coin into a boat shape - it would float.

Displacement.
If you flattened the coin and shaped it like a ship's hull, it too would float.

Big ships have air trapped inside their metal hulls. If the hull is broken and water fills the hull then the ship will sink.
