@shiva, I think your coin is a Mansfeld-Friedeburg thaler like this one: https://www.coinarchives.com/w/lotv...2a8341f9ae01
As you can see, this one had also been mounted in some kind of fixture previously. It does diminish the value, but it happens often enough that there is still a market for coins with a defect like this.
DO not do anything to remove the dark patina on your coin; this will make it less desirable. You coin has more wear than the one in the link, so I would expect the value to be somewhat lower.
