Dice once needed stamps to prove taxes were paid

Why a die needed its own tax mark

A tax on dice was difficult to enforce if officials could not tell whether a particular die had been taxed. Putting the official stamp directly on each die made the proof travel with the object. A stamped box or receipt could be separated from the dice; a mark on the die itself was harder to detach from the taxable item.

That approach turned a tiny object into a miniature tax record. The stamp signaled that the required duty had been paid, allowing officials—or buyers—to distinguish marked dice from untaxed ones.

A mark worth counterfeiting

The system also created an incentive to imitate the mark. A forged stamp could make an untaxed die appear legitimate, letting its maker or seller avoid the tax while competing with lawful goods. Because dice were small and the stamp itself carried the proof, the mark was both the enforcement tool and the target of fraud.

The result was an unusually literal form of tax compliance: on every die, the evidence of payment had to fit on the thing being taxed.
