What are spy coins used for?

Hollow coins, a cunning method of concealing secret information, have been employed for years. Their unique design allows for the seamless insertion of microfilm and microdots, making them an ideal vessel for transmitting covert messages.

The intricacies of these coins lie within their hollow interiors, which are meticulously crafted to house delicate items without compromising the coin's overall appearance. This feature enables users to transmit sensitive information without arousing suspicion.

To access the hidden contents, a precise technique is required. The process involves delicately inserting a needle into a minuscule hole located on the front face of the coin. This action must be executed with utmost care to avoid damaging the delicate materials housed within.

Once the needle has successfully penetrated the coin's exterior, it can be manipulated to extract the microfilm or microdots. The retrieved items often contain vital information, such as secret codes, maps, or messages, that are crucial for various covert operations.

The use of hollow coins as a means of communication underscores their versatility and ingenuity. They are not only aesthetically pleasing but also highly functional, making them a valuable tool for individuals engaged in espionage or other sensitive activities.
