Hello,
I have this couple of 1 Pice 1943-44 - George VI coins which are underweighted. Catalog weight is 2 while real weights are 1,67 g and 1,88 g
Is it normal for these coins?

mine are between 1.85-1.90, so as usual it's numista which is wrong (based on KM!!).

Yes it is totally normal...weight difference is due to common circulation. These are used coins and that's why they weigh less

Since these coins are of low denomination,ther was no attention to detail during the minting process

KM says 2 grams and in reality it's always less than 2 grams. Around is no good!

Cita: "Akk" Then we should say " variable weight : 1-2 g"No way, instead we should ask everybody having any af the coins
km432 (
https://en.numista.com/catalogue/pieces21213.html ) and
km533 (
https://en.numista.com/catalogue/pieces1613.html )
to weigh their coins and then we take the average for numista
I'll start with my coins:
1.91 grams in average on 7 coins

Cita: "Meet H Dand" Yes it is totally normal...weight difference is due to common circulation. These are used coins and that's why they weigh lessNo. Assuming 2 g nominal weight this would be 16.5% and 6.0% weight loss due to circulation wear. 16.5% loss is way more than normal for even heavily worn coins, which this one is not. 6% is even a lot more "wear" than can be accounted for by the condition for this coin.

In my example the delta on the average weight goes from -2.85 to +5.03 which is nearly 8 grams!

Cita: "rsirian1" I knew one of us was confused. I'm even more confused about the crowns on those 1 pice coins
Since I took them all out to make sure the measurements were OK, I also started to verify that they had been catalogued correctly, so now I'm in small dots and bigger dots, flat, high and round crowns and that is frustrating when you don't have au to unc specimens in front of you. I suppose another hour will be spent before I've everything in order.

There are two definitive versions of this coin one with a low crown and one with a high crown.

Cita: "Grinya" Thanks. with using the average weight of 1.91 it's only 12.57%, if my excel is correct. Don't use 2.00 grams (16.5%!).
