Answer to "Golden and coloured Coins"

There are two clues in the picture, one is the multi-coloured sunset background and the other one is the coin shapes. While most coins are round, there are some merging together, few overlapping. This means the objects must be liquid. In order to be there, there must be a surface which allows the liquid to stick on. The common liquid is water and the common surface is glass, so the objects must be liquid drops on the glass panel. If you look at the liquid drops against the sunset background, you probably see faint coloured drops. But if you taking pictures at an angle, intense multi-colours would appear due to the law of Physics, refraction of light.
