5000 Gulden

Suriname's 2000 currency reform was driven by a decade of hyperinflation that had reduced the gulden to a fraction of its former value — the 5000 gulden note, once unthinkably large, became an everyday denomination simply to keep pace with prices. The country would abandon the gulden entirely just two years later, replacing it with the Surinamese dollar at a rate of 1000 to 1, which rendered this entire series obsolete almost immediately after printing.

Thomas De La Rue's security package here is relatively modest given the face value — watermark and thread, no optically variable ink — reflecting the practical reality that a currency slated for near-term replacement warranted no substantial investment in advanced counterfeit deterrence.
