What to do if I already bought a haram coin and after checking this website just now I found out it was haram.

I bought maybe 7 of the coins on the list that is confirmed to be Haram. I didn’t think they were at the time and now that I saw this website I just don’t want to have haram money I still didn’t sell any of them. Should I sell it and give it as charity ? Or what do I do with that money that is now haram?
