Experts in intelligence and cyber security said a 14-year-old boy solved the most difficult code on a silver coin in just one hour. The code was made up of numbers and letters.
A cyber security team in Australia that works with foreign intelligence made a 50-paisa coin with five levels of code on it. A Tasmanian boy solved four of the levels of the puzzle in just one hour. But the fifth stage is very hard, and no one has been able to figure it out yet.

The Australian Signals Directorate (ASD) put out the coin on Thursday to celebrate its 75th birthday. On its back was a five-level code or puzzle, with each level getting harder than the last. On both sides of the coin are hints about how to solve the puzzle. However, after an hour, a teenage boy explained all four levels, which surprised even the experts and coders because it was such a hard challenge.
At 8:45 a.m., a detailed picture of both sides of the coin was released, and the public was asked to fill out a form to solve the puzzle. A 14-year-old boy answered the form within an hour, which was a surprise. He was from Tasmania, and he had figured out the four-level code puzzle correctly.
