Russia 5 kopek 1803 C#115.1 EM + variant [solved]

Two coins C#115.1 but very different - both are minted in Ekatrinburg, left coin is 42,3 mm, 53,58 gram and 4,9 mm thickness, right coin is 50,11 gram,41.8 mm and 5 mm thickness.

The right coin is almost identical with C#115.2 KM but mint mark is EM. Is this a common variation or is it rare? Should this variation have had an identification number? Please comment.

Kind regards

The circled dots on the right hand coin are interesting. I don't recall seeing that before.

I wouldn't say “almost identical”, there are many differences between the right and 115.2. But I'm only looking at the Numista images and your images – I've seen lots of variations in these coins before.

Please include links when you talk about coins in Numista. Save people the trouble of finding them.

This is a picture from Krause showing C 115.2. The dots with 2 circles is almost equal with the right hand coin. The mint mark KM is on this coin is on the obverse divided by the eagles tail. The right hand coin looks to me as a product of  Suzun Mint insted of Ekaterinburg even the mint mark is EM.

The left one is Bitkin №284, the right one is Bitkin #287. Both are common

Thank you very much.  It's great to have a so helpful participant in this Forum.

Conclusion is that Bitkin #287 is a variant of C# 115.1 and is minted in Ekaterinburg - if  I understand right? Are there any difference in value of this two coins if we adjust for the condition?

Kind regards

The technologies for making coins in the Russian Empire until about the 1830s did not allow making completely identical coins in weight and diameter. The whole batch of coins, and not each individual coin, had to correspond to the normative weight; therefore, if there were too many lightweight coins in the batch, then a very heavy one (up to 1.5 times heavier than the standard) was added to it, and if there were too many heavy-weight coins, then a very light one (up to 2 times lighter than the standard). Your two coins are almost identical in weight and nearly match the standard. Now, if you find 5 kopecks weighing 25 or 75 grams, then they cost more.

Thank you very much for the information. This was unknown knowledge for me.
