After the change to the Euro, the euro countries scrapped their old coins to sell them for scrap. But to get the most money for the metal, the coins were kept in warehouses until the markte price was high enough to sell part of them. Meanwhile, to preven theft (since the old coins could still be converted to Euros), the coins were made unusalble.
In the Netherlands, the old guilder coins were wrinkled in a special machine, at the Dutch Royal Mint. The Mint sold a number of thiose wrinkled coins to a company called MuntPost (known on Numista for their medals and tokens). MuntPost made sets of them, and sold them to collectors in a special “Farewell to the guilder” set:

The wrinkled pieces of metal are still recognizable as former coins.
My question is: is there a place on Numista for these scrapped coins? If so, in which section? They were produced AND altered by the Dutch Royal Mint.
Please let me know your opinion about it.
