The Netherlands has a rich history in terms of gold coins used as legal tender at the time. The gold tenner was first minted in 1818 in the era of King Willem I, the last gold tenner was minted in 1933 (Queen Wilhelmina).
In addition, gold fives and single and double ducats were minted in the Netherlands. All these coins contain 90% gold. In the past, these coins were collected distinguishing by year. Nowadays, the gold value has overtaken the collector's value (with exceptions) and these coins are traded for a low premium compared to the current gold price.
