A rare and exciting opportunity to acquire an object at the crossroads of history, technology, and numismatics:

A genuine deactivated bank dye security device, concealed within a stack of hollowed-out $20 bills. This iconic device, often seen in crime films and TV shows, is a “dye pack” designed to combat theft.

Originally hidden within a bundle of banknotes, this pack — model SecurityPac/FlexPac FX-10, manufactured by 3SI Security Systems, Inc. was programmed to detonate as soon as the signal from the bank vault was lost. It would then release an indelible dye, usually red or blue, staining not only the stolen cash but sometimes the thief as well, thereby facilitating arrest and rendering the money unusable.

This exceptional specimen, dated July 18, 2005, reveals the inner workings of such a device, featuring its original electronic circuit and a dye pack stamped SecurityPac. It is carefully housed in a custom PCGS-sealed display case, ensuring both its authenticity and preservation.

At once a tool of criminal deterrence and a unique collector’s item, this pack is a tangible fragment of an era of high-security banking. A rare piece, perfect for enthusiasts of criminology, security technology, or financial history.
