Italian 20 centesimi 1939 [gelöst]

I have been going through my Italian families 20 centesimi coins and I have a 1939 20 centesimi that has a lot of unique qualities, 1st while the coin is slightly magnetic it is a lot less than my other 20 centesimi coins, while you may think I'm just overthinking some strong magnets will stick to the coin but weaker magnets won't while the same weaker magnets will still stick to my other 20 centesimi coins, it also weighs less than my other coins and it only has some micro scraches  with close to no circulation wear that could do this, I'm thinking it could be this coin (N#11201) as it weighs the same amount as mine but the one I have is reeded, could it be an U catalogues coin? I have really no idea what to catalogue this item as magnetic or non magnetic circulation, or something else, thanks forn any and all help. And if needed I can try to upload a video comparing the magmatism please just ask, thanks again.

This should answer your questions.  You have different types of similar coins.  https://en.numista.com/catalogue/index.php?e=italie&r=&st=1-2-3&cat=y&im1=&im2=&ru=&ie=&ca=3&no=75*&v=&a=1939&dg=&i=&b=&m=&f=&t=&t2=&w=&mt=&u=&g=&se=&c=&wi=&sw=

Keep in mind some stainless steels that are considered “non-magnetic” can develop magnetic properties when cold worked (such as being cold worked by a minting press). The level of magnetism will depend on the amount of cold work and may appear as non-magnetic with a weaker magnet and magnetic with with a strong magnetic. A good example of this is a stainless steel sink.  The large flat portion may appear to be non-magnetic but at the 90° bends it will appear to be magnetic.

it also weighs less than my other coins  

Don't be mislead by the weight. Every coin is struck with a weight tolerance. Your 3.95 gr. is perfectly in range with all 4 types so you can't use the weight to determine the type.

A magnetic coin should stick to any magnet, weak or strong. When yours doesn't stick to a weak magnet, you have KM# 75d, the non-magnetic reeded edge.

thanks both of you, i just didn't know what to think about the partial magnetism, thanks for the quick and simple response, i know other places aren't as nice when stupid questions get asked but you were all very nice, thanks again

I would like to add there are no plain edges. So there is 3 types. Your coin would be non magnetic, as explained already - the steel composition and way of planchet production seemingly differed from early ones to the later. With ordinary “weak” ferromagnet the difference is usually very clear.

As these coins were in use in my hometown as well at the time, I have seen a lot of examples. It was a short living occupying force in Dalmatia and literally most of people have these coins somewhere in home, if they kept them during the years. There is however sometimes a minting error with very weak and usually partially reeded edge. 

Please note the italian catalogs (mostly) do not differentiate them for that reason

And refer also to this post for instance

Note how there is a mention of completely plain edge with lesser diameter which is clearly a manipulation.

 I assume you mean there's no KM# 75c, because when you say there are 3 types one of the three must be a plain edge!

The Italian catalog "Alfa Edizioni - Torino" doesn't mention the non-magnetic plain edge but they do mention the magnetic plain edge and for all three dates.

They also stipulate the plain edge coins have a slightly bigger diameter of 22.5 mm in stead of 21.8 mm, so these certainly can't be filed reeded edges:

Exactly, that's why I said mostly. On the italian forum they mention Alpha. It should be slightly larger diameter for the genuine error, of course. If diameter is smaller (like the example mentioned on the forum) it is almost certainly a manipulation.

Is this catalog available online or is this your personal scan?

This is a personal scan. You can see it here with my first attempt:
