Hello everyone, I am fairly new to the scene here and I have a question I hope someone can help with. I was wondering if it is necessary to hide the certification numbers of my coins in my registry sets? I see that some people do and some don’t. NGC hides them, so it made me curious if it was a good practice, done for security purposes, counterfeit measure, or if it mattered that much. Below (or above, wherever this picture ends up) is an example of how my coins are displayed at the moment. I would appreciate any feedback. Thanks,
