I believe this is what you have: https://www.ma-shops.com/kornblum/item.php?id=190729018 there's one for sale on eBay https://www.ebay.com/itm/1670-Swede...144349?hash=item56c872a65d:g:CwsAAOSwSv1XlQyS
Sweden, 1670, denomination: 2 Mark, KM#242, .6940 silver, mint-Stockholm, Bust of Carl XI, mintage-802,000. Info taken from my 2003 3rd edition 17th Century World Coin catalog grade/value VG-$25.00 F-$60.00 VF-$125.00 XF-$220 values could be higher now. I do not know the grade of your coin ???
I don’t think it will straight grade with the scratches and damage. Won’t be a good bet for grading imo.
The one listed on peebay is way overpriced for opening bid. Seller has dozens of auction listings with none getting a bid. All too high
