Oudewater held out against Spanish forces for less than a day on August 7, 1575, which makes the survival of any siege coinage from this town extraordinary. The Spanish sack was immediate and catastrophic — the garrison was massacred and much of the population killed. Whatever emergency pieces were struck had almost no time to circulate, and most would have been melted, lost, or destroyed in the violence that followed.

Tin was the material of last resort, used when silver was exhausted or hoarded. At 37 grams, this piece represents a substantial casting rather than a struck coin in any conventional sense.
