Thats why I referred you to that site I posted, with Sedwick, your guaranteed it's real. Ive bought a few coins from him with no regrets.
well I did see this one on ebay Treasures of Maryland and theres one that im looking at that is real but it is 5 bucks for a COA certified by a pro so i might get that
You might want to be a bit hesitant for there are plenty out there who will sell you a meaningless piece of paper. Just because they call it a COA and say it is issued by a pro, that doesn't mean the person really is a pro or that the coin is even genuine for that matter.
