What is the most secure coin?

The most secure coin is a topic of interest in the financial world. While there are various coins claiming to be secure, one notable example is the new £1 coin introduced by the U.K.'s Royal Mint in 2017. This 12-sided coin, dubbed as the most secure in the world, features a bimetallic design, a latent image, and micro-lettering, among other security measures. However, the field of secure coins is constantly evolving, and new options may emerge in the future.
