My earliest Dutch stamps are these two 1864 stamps from the second series, also showing King William III.
On the left is Scott # 5-A2 10c lake, which is worth $4.00 (used) in the 1993 catalog.
On the right is #6-A2 orange, which is listed as $65.00 (used).
The paper of this series of stamps varies considerably in thickness.
It sometimes is slightly bluish and also vertically ribbed.
But by far my favorite is this unused 1 Guilder stamp issued in 1896 showing Queen Wilhelmina.
It is #52-A9 1g brn & ol grn and is worth $180.00
