Greetings. Just FYI, neither ICCS nor BCS have an online verification tool on their respective websites. Therefore, Numista doesn't have the ability to provide a link to any details for certified items from those 2 companies.
Do you have a list of the grades that can be given by these companies?
The list provided by CSSS at https://cccs.co/coin-grading/ doesn't seem to be exhaustive. Here are a few examples I gathered that are not from the list
I have contacted these companies for their list and they haven't gotten back to me. We are about to send some stuff to ICCS and CCCS and we will ask for a list with the request.
