I recently got this coin:



And it has the edge of this:



Nice grade, Uzedenikov has marked it as scarce and I don't believe I have seen many examples of it, so I'm happy with the price I paid for.

It seems that in 1811, this is the ending of the reeded edge of 2 kopeks. Why? Is it because people found that out copper prices were too low (hence scrapping copper was worthless) and milling such coins were too expensive and hence the mints started to abandon them?

(People here always know more stuffs than what I know, even some of the most obvious coins )

Congratulation! This is a great example of this scarce coin. I specifically collect 1811 by variations, but my exemplar is much worse. It is not hard to find this variant, but it is extremely hard to find it in a decent condition. If I ever show something you like, offer this one for a trade.
