Denmark coin with "heart" - id please [solved]

For days I'm looking at Internet sites, forums, numismatic catalogs, but without success ...
I think that it is a coin from 1690 to 1700 with Christian Winnecke sr mint-mark.
The coin is left in the photographs, the right side is the Croatian kuna for comparison.
I know that the coins in very poor condition, but please help me, there is enough detail that can not be confused with any other coin. Maybe coin has no connection with the Christian Winnecke, but in a few cases where the coins were also marked with these mint-mark, the currency was not skilling.
The first word is probably "SKILL" like this coin https://en.numista.com/catalogue/pieces22576.html
How is it possible that I have found the coin which can roughly determine the origin and date, and I can not find at least similar on the Internet? Thank you in advance for your reply and sorry for my bad English!
