50 Centimes - Balduin I

I was adding coins from Belgium to my collection until I get to the 50 Centimes of Balduin I.

I readed in both links of this coin (the one with French and the other with Dutch text) that there is a Type A and a Type B - with a few physical differences and probably the most important with different KM/ (Dutch Type A KM/145 vs Type B KM/149 - French Type A KM/144 vs Type B km/148)

As I understand, in both cases Type A is the weird one and Type B the normal one, because it's only listed the Type B (there is also a Type C, but again, I think its another normal one because its listed).

Coincidences of life, I have 2 coins, one of each text from Type B (Dutch 1977 - French 1959).

So my question (request sounds too powerful to me), should not this different KM/ should have his own lines? Shall/Can I help at least creating the ones for my coins?

Regards

It looks to me like the Type A coins have their own pages.

For the Dutch coins, here is Type A: https://en.numista.com/catalogue/pieces5333.html.
(And the Type B and C one: https://en.numista.com/catalogue/pieces752.html.)

For the French coins, here is Type A: https://en.numista.com/catalogue/pieces5332.html.

Well, with this, its the second time for me in a row that using the advanced search in the catalogue, some coins don't appear or i miss them (i would guess that this time it didn't appear to me, only appear the ones that i linked before) so i will stop posting, I need to be doing something wrong.

Thank for your time and sorry Sulfur and all the Numista team

There is no need to apologize--everyone makes mistakes.

And of course, mistake-making leads to experience, so you should certainly not stop posting because of them.

Sulfur, one last thing if you can help me.

I've spent the whole week away from my coins so I was going to add them now in the correct links that you posted, but there is no line for none of my years (Dutch 1977 - French 1959)

I do not want to edit anything seen the problems that I had previously, shall i ask the country refree about this?

Just this weekend i left my scale in the office so i cant show photos about the measurements i did to prove that this is the Type A (i measured the line below the crown giving me thoose 6.8mm)

Your coins are in the catalogue all right.
Type A is only till 1954, as from then they are all on the other page with B/C types.

If you think you found a new variety, please post pictures here.

​I dont think i founded a new variety but i will come back with pictrures (with scale) this week of theese 2 nightmares

Yes, pictures would definitely help.

With the differences being so minor, I am not exactly sure why these Type A pieces and these Type B/C pieces have... well, their own pages. Sure, The type A page is for the large head and the Type B/C page is for the small head, but the comments say Type C is actually a large head? I don't know--it confuses me, so contacting the referee may be your best option.

​I am doing all this noise because this explanation image:

That you can find in this link (50 Centimes - Baudouin I French text):

https://en.numista.com/catalogue/pieces1239.html

I have to emphasize that i measured the crown, giving me thoose 6.8mm "small crown" that would correspond to the KM#144 (as you probably saw, all is explained in the explanation image too) and that leaded me to this post in the forum, blablabla.

I need to say too that the other measures, specially the ones related to the head, i found them a bit tricky so in the end i didnt try thoose, but i will try to come back this week with pics of all this measures, etc

​First of all, sorry for left this uncomplete for months... Work, Phd, etc i wasn´t able to nothing related to coins. I hope my new reply will help to make justice.

Well, lets remember. I found 2 coins of 50 cents with french and duthc text, 1959 and 1977
respectively.

Here in numista some users noticed that there are some varieties of this coin: This is the info given (i adapted and order it to be standard for all types):

KM#144 (Type A): larger head (16mm), smaller crown (6.8mm) and letters; legend far from rim (easy to see)
KM#148.1 Type B: smaller head (15.4), larger crown (7.3mm) and letters, broad rim (1.1mm)
KM#148.1 Type C: larger head (16mm), large letters, broad rim (1.1mm)

At first the question was why only Type B and C have mixed lines (by type) in 2 different pages (by languages) but it tourned out that there was lines for that Type A in 2 different pages by languages that i wasnt able to find.

So, knowing that there was no fault in numista catalogue (that was my concern) i tryed to see if my coins matched some of this aspects. With a scale i tryed the easy one, the crown; results matched Type A but for Type A is only listed from 1952-1955 french text and 1952-1954 dutch text.

So, a few months ago I had to leave this topic in the point that i was going to give you pics.

Here i am and here are the pics. I used a pc program called AutoCad that probably you might know, its used by architects, engineers to make blueprints and stuff like that. In this case i think is the best option to give you concrete info (hope you undestand my bad english explaning this things).

First the scales of both sides (0.05cm = 5mm) you can see that i used a paper scale of 5cm, wich i scaled in the program to have real measurements of the coin.



For the side of the head i did a line in the first coin and copy-pasted in the second as it matched perfectly, you can see the results: 15.4mm = SMALLER HEAD = TYPE B



For the side of the crown i couldnt use the same line as i thougt it didnt matched well, here are the results of both crowns:
1. 77 = 6.9mm = SMALL CROWN - TYPE A
2. 59 = 7.1mm = no man's land?



No info is given for the other measurements (I'm not criticizing the work of Essor Prof and Ole Sjoelund) but i measured the lighthouse (a bit different like the do) and i had the same measurements in both coins of 1.7 mm (If it helps there is the data)



I also measured the face to helmet and i had small differences:
1. 77 = 11.2mm
2.59 = 11.4mm

And i would say that my letters are the bigger ones (comparing them with the photos of the links= = Type B and C

After writing this new chapter of a rookie playing with coins i realised that if i had done the pics with only 1 coin i would have 99% better measures, but for instance, for the 1977 one there are 2 results (head and crown) that probably will not change too much and speack about two different characteristics from different types mixed in that coin.

If you have arrived here... what do you think?
