Theoretical syndicate currency

On Emergency's world there has been some discussion about what a syndicate's currency "could" look like. There has been a few flying around like other governments currency, bartering, and other typical currency. But the one that has floated around the most is that the coins used is the metal that backs it up and there are three layers to the coin(which there is no 'bill' and only one variation of coin like the currency in the John Wick movies) The outer layer is gold with the imprint that describes the information in the inner layer. the second layer is an RF shield that protects the inner layer. Finally the inner layer is a small storage chip that holds a world changing secret like how to control the weather, what is in the Vatican archives, what is in the Marianas web, where are the aliens, and every little secret of every politician to the point where if that information got out that, that person would get arrested and shot on site all over the world. Not only is the metal the syndicates backbone to the currency but also the secrets stored within.
