This copper coin is slightly worn, just like every other trinket of currency common throughout Timeaus.
A thieves' token is a Timerian copper coin that has been subtly modified with almost undetectable indentations and symbols. Each guild has their own unique pattern and any two thieves' tokens can be placed face to face to fit smoothly together. A DC 20 Disable Device check is required to put the coins together and determine if there is a fit (and no other coins are able to make a seamless connection). The means of their construction is a closely guarded secret. A thieves' token has a magic aura of conjuration and anyone that attempts to identify its magical properties believes it to grant a luck bonus to saving throws, but a DC 25 Spellcraft check reveals that this is merely the effects of a magic aura and nothing more.
DC 15 The various thieves' guilds that operate underneath Nyamo have a foolproof way of identifying their own members.
DC 20 The Order of the Staff would pay dearly for information on how to infiltrate the underground criminals, something that they have been unable to do.
DC 25 Most underground thieves' guilds employ at least one expert counterfeiter.
Requirements 1 cp, DC 30 Profession (jewelsmith) check, magic aura; Cost 500 gp
The guilds needed a foolproof way to identify themselves to each other that is difficult to magically locate; to disguise the true purpose of the coin, a permanent magic aura is cast on it. Lower level operatives are told that the thieves' token grants them magical luck, while higher level operatives are told to tell anyone examining the coin that it provides magical luck. The enchantment is pure subterfuge, meant to deflect attention away from the real (mechanical) purpose of the coin.
