I gave you the information on these stamps yesterday. I shall post it again below.
As Cursus posted, these appear to be stamps of little value. You might be lucky and have a perforation or watermark variety, but as the obvious stamps with some value - and even that is not much - are missing, these, likely are the stamps used in the millions on correspondence.
These are Dutch stamps.
First two are known as 'Crouwel's' and were in use 1976 - 2001. The top and bottom imperforate stamps are from counter rolls.
https://goscf.com/t/79374The next few and also the first ones on the second row are 'Van Krimpen's' and were issued in 1946, after the liberation. They were in use until the 'Crouwel's' were issued. You are missing the key 2 1/2 cent value. These, also, were issued in the Dutch colonies.
Numerals were used for rates below the basic letter rate (e.g., on printed matter). The basic letter rate and higher values showed the monarch.
The stamp top right is one from the set issued in 1947 showing H.M. Queen Wilhelmina. They were issued shortly before she abdicated. They are known as 'Hartz.'
The 'numerals' on rows 2 (right) and 3 (left) are 'Lebau's.' They, also, are known as 'Flying Dove.' Scott calls them 'Flying Gull' but that is nonsense. They show a dove over the waves and not a gull. These were introduced in the 1920sand remained in use until the occupation. They come with and without 'rings' watermark. They also come with syncopated (coil) perforations. Yours all have normal perforations. Those with watermark come in lithography and photogravure. Look out for the latter.
After the occupation, the Germans did not want to use stamps showing H.M. Queen Wilhelmina. So, the 'Lebau's' were reprinted in green and overprinted with a 'Guilloche' and value. The high values are pricy, the lower ones are not. The 2 1/2 cent was used for postcards and had to have a red colour. As it was issued se-tenant with the 7 1/2 cent for rolls of stamps, the 7 1/2 cent also was printed in red.
We also call these 'traliezegels' referring to the occupation (tralies = bars). You have the 7 1/2 cent 'Guilloche' or 'Traliezegel.'
The next two are of H.M. Queen Wilhelmina, issued in 1940, just before the German invasion. They were reprinted after the war and specialists recognise the papers. These are known as 'Konijnenburg' and were replaced by the 'Hartz' stamps in 1947 and 1948. These are the stamps the Germans replaced with the 'Guilloche' stamps. A few also exist imperforate.
H.M. Queen Elizabeth appears to be visiting H.M. Queen Wilhelmina. But it is not a Dutch stamp.
Row four shows the 'En Face' stamp of Queen Juliana issued 1941-1951. The details of the stamps were not very convenient for mass printing in photogravure. In 1953, they were replaced by the 'En Profile' stamps that are the next two on the fourth row. Another 'En Face' stamp follows those. one 'En Profile' stamp (12 cent) comes with yellow fluor, together with the 4 cent and 8 cent 'Van Krimpen's.' They also come with phosphor coating. They exist with numbers on the back from stamp rolls and with imperforate edge from booklets. The latter also exist with phosphor coating. (All three Queen Juliana sets were designed by Sem Hartz. Naming them after the designer as is common would not work.
The last two on the fourth row are from the 1899 - 1921 set known as 'Bontkraag' (fur collar) of H.M. Queen Wilhelmina.
The fifth row starts with 'Veth' stamps of Queen Wilhelmina. Three stamps were issued for a stamp exhibition in 1924. The series ran from 1924 until 1940 and exists with and without the 'rings' watermark. They also come with the syncopated perforations for paste-up stamp rolls.
The final two are numerals (below basic letter rate) stamps of the 'Vürtheim' type issued in 1899. These complemented the 'Bontkraag; stamps.
At first sight, all are common stamps.
