I am wondering how scarce is 1736 Denga struck over Peter I Kopeck, coin is with plain edge. It is well known that in 1730-1734 Peter I Kopecks were overstruck in Moscow and those coins (with plain edge, dated 1730-1734) are quite common. But I was unable to find reference to 1736 coin. May be someone knows how scarce it is. Thank you.

I believe the overstruck event was from 1730-1735 according to Uzdenikov. 1736 would be very unusual - I presume you have a coin that seems to be so? If so, please kindly show a photo of it
