Our Online Join feature is a streamlined, easy-to-use tool offering 3 ways to pay – you can pay using a credit card through PayPal, you can also pay using your own credit/debit account, and you have an option to pay with a check by printing out an invoice and mailing it and your check, to RCGS. Your transaction is not complete until you fill in the box with the number that it shows you. This is to assure you are not a robot. It's easier than ever to become a RCGS member!
