Theory#qqxwre7v
There are claims that US dollar bills contain hidden images or markings that are not visible to the naked eye. These alleged images are said to be embedded in the design of the bills, specifically in the serial numbers or security threads. Some researchers point to the 1996 redesign of the $100 bill as a possible example.
The 1996 $100 bill redesign included a new security thread that glows pink under ultraviolet light. Some theorize that this thread may be used to conceal hidden messages or images.
Reason
The reason for this theory is the unusual design choices made in the 1996 $100 bill redesign. Some researchers have noted that the new security thread seems to be more than just a simple anti-counterfeiting measure. The lack of transparency from the government about the design process has fueled speculation.
