Hi luc87, The 5 guilder (as the whole of the guilder-system) was legal tender until Dec.31, 2001. On Jan.1, 2002 it was replaced by the euro-system. There were no guilder coins issued in 2002. To get everything right: 2 of these coins were struck with date 1987.
Strictly speaking, the guilder became part of the euro system on 1 January 1999 and continued to be legal tender until 28 January 2002. Oh, and there was a second 5 G piece in 2000 (the football coin) but that one had the same technical specifications as the regular pieces ... Christian
5 guilder coins were legal tender, not meDals! The meTal composition of the coins you asked about was nickel and bronze, as posted previously. I know the modern approach is "Who the %$@#$ cares about correct spelling?", and I guess the schools don't teach it as a subject any more, but I really get upset about confusing such elementary ideas as "medals" and "metals".
