The world’s largest auction platform for coins, Sixbid, informs its users that scammers send fake invoices to Sixbid bidders. These are easy to unmask as soon as you know what to look for. Sixbid asks anyone who has received such an email, to forward it to Sixbid to help criminal prosecution.
It’s almost impossible to imagine the world of coin collectors without the grading company NGC and the auction platform Sixbid. NGC has now been named the Official Grading Service of Sixbid. This step further strengthens the collaboration between the two companies.
