When the euro cash was introduced almost four years ago, a Dutch music store chain ("Free Record Shop") prominently advertised that customers could pay using guilder (NLG) coins and notes even after the end of the dual cash period. Now the company sits on a bunch of worthless cash.
The Dutch central bank DNB had repeatedly refused to change the guilders from these stores into euro cash. A week ago the Raad van State (highest administrative court in NL) decided that the bank's position was right.
While NLG coins and notes can be exchanged into euro cash until 2007 and 2032 respectively, that offer is limited to individual customers. Also, the DNB will only accept NLG cash that the customer had before the deadline. Of course you cannot actually tell when exactly somebody acquired this or that coin or note, but I guess the idea was to prevent excessive money laundering. This Dutch regulation is unique in Euroland.
Well, now the company has a problem - lots and lots of "worthless" guilder cash. And what does it do? It sells the coins and notes as, ahem, souvenirs:
