The Netherlands issued their own coinage, but now only use Euro coins; the old coins are, in fact, no longer valid. But since it looks like the Euro and the European Union might be in trouble and hopefully disband, their old coins might just become very collectable. One of our suppliers has put together type sets of the old, pre-Euro coins that each country used to use. It is getting harder and harder to find the coins to make up these sets, so supplies are limited. All coins are circulated, which means that they were actually used as money. You get the 5 Gulden, 1 Gulden, 25c 10c and 5c coins.
