What happened to this coin? (2) [solved]

Hi again,

I have in my collection a Belgium 25 Centimes 1946 coin (KM# 132) with a diameter of 24 mm, which is exactly 2 mm smaller than the normal version. The coin weighs 5.36 g. (6.5 g. for a normal one). The coin is in my opinion UNC quality and does not show any damage as a result of any manual handling. The center hole is inside also without any damage.

I'm guessing this isn't a PMD example, either, nor is it counterfeiting.

Could this be a coin struck on a wrong blank coin plate?

I'm of course very curious about your opinion...

Regards.

PMD, post mint damage, somebody turned the edge off, that's all.

I looked at this, and was thinking it could be on 10 centimes blank. A 10 c has dia 22 mm and wt of 4g. But yours has the weight 5.36. I would agree with Ole. Someone cut edge off. PMD

The 5fr from that year come a bit closer in diameter, but I'm not sure when in the production process the hole is being made … is it before or after minting? Though I guess still too wide and too heavy (the hole cannot at once loose 0.6g) …

No other zinc coins were produced in Brussels in that period, so most probable explanation looks like a trimming job well done. The coin doesn't look UNC to me, looking at the wear on the shields … 

The fact this coin has an hole, made it very easy to put it in a lathe en machine it off.
The question is ofcourse;  why would someone do that?

I just wonder if you can clamp the coin in a lathe without visible damage afterwards? If this can be done effectively, then I also think that this is the most obvious explanation for my then 'worthless' coin... 😉

Thank you all for responding to my post.

If you measure the hole and you find, or fabricate, a small bolt who will fit in that hole exactly.
Than you make 2 plastic washers and use a nut on the bolt once you put it in the coin. If you did that it is very easy 
 to clamp it in the lathe….If you like I will make one for you, just let me know…

Thank you for your offer, but... I don't have a lathe ! 😊
