Some guilder banknotes may be exchanged at DNB up to 2032. Guilder coins (including ten-cent, twenty-five cent, and two-and-a-half guilder coins) are no longer exchangeable.
The guilder notes may be presented at, or sent to, DNB in Amsterdam. In either case, they must be accompanied by a completed 'Exchange application form (to be submitted over the counter or by mail)' form and a valid proof of identity.
