20 коп 1982 вес монеты

Добрый день.

Попалась вот такая монета с завышены  весом я так понимаю ето на заготовке 50 копеек? 

Только не понятен вес она намного больше весом? 

Прошу помощи експертов? 

Заранее спасибо за данную помощь и за ответ. 

Хорошего дня всем

It is too light to have been made from a 50 Kopeck planchet. What is the diameter? It also seems to be too heavy to be a normal 20 Kopeck coin.  Numista has the weight as 3.4g but SCWC has 3.3g and my coin has 3.3 g.  Your coin at 3.76g is 14% overweight, too high to be normal tolerance.

Да она превышает номинал 50 копеек.ширина монеты такая же но толщину монеты на етой неделе дам знать нет чем проверть

50 kopeks are 15% thicker than 20 kopeks. It fits 3.7 grams, but there is no explanation why such overweight variants are not listed in catalogue that pays attention to design details.

Добрый вечер. 

Как обещял делать фото. 

Сори что так долго, ждал прибор. 

Hard to tell, it that measurement on the rim or just off it?

My coin:

Weight 3.294g

Diameter 22.0 mm

Thickness center 1.17 mm

Thickness rim 1.30 mm

Year 1961

Condition some wear ~Fine

А монета 20 копеек 1961 хорошая 

За долгое время нашол одну только с таким весом. 

So 1.27 mm in center and 1.39 mm on rim.  

Same answer I originally gave, too light (and small) to be a 50 Kopeck planchet and seems to be too heavy to be a 20 Kopeck planchet but  I don't know the quality control of the mint there at that time so I can't say for sure.

Вес монеты котой предоставил 20 коп 1982

Maybe Ole can tell us the weight of his 20 Kopeck 1984?  @Sjoelund 

1983 - 3.37g

1984 - 3.23g

1985 - 3.24g

1986 - 3.29g

1987 - 3.35g

1988 - 3.38g

1989 - 3.43g

1990 - 3.34g

1991 - 3.36g

Ну да. Я думаю ето на заготовке 50 копеек

With pleasure, I haven't weighed all of them, but here are those with a weight!

Thanks

I think, the OP's instrument is prone to the subjective reading of the micro meter. Use a digital instrument, please?

Спасибо большое за ответ

Может кто знает как высчитать объем монеты на сантиметр кубических? 

Forget it. There's too much error associated with calculating the volume since the thickness is not uniform and not easily measured, the reeded edge is too complex to get an accurate volume, etc. If you want to measure the density do it right:  https://en.numista.com/numisdoc/determining-the-metal-of-a-coin-27.html but you'll probably still be confused since experimental errors can be large such as using a very heavy glass cup and water 25 times the mass of what you're trying to measure.

Спасибо большое за ответ. Какая цена такой монеты?
