Grandmaster Supreme Poobah

Thanks.

Hello, I'm sorry to bring this matter up using the Forum. Admittedly, it's a little embarrassing for me to bring it up in a public forum setting. I hoped for the issue not gaining unnecessary attention. I've sent a message regarding the issue using the Help Form inside the Registry, but haven't received a reply, nor a solution. No pressure at all. Maybe I can get a little feedback here, if possible. Please excuse the blunder, if I've gone about this the wrong way. I've just completed one of my Sets, and there's a coin that I own in my Registry that also appears in another Collector's Set Registry. Apparently, the coin was once graded and encapsulated by NGC, but is now in a PCGS holder under my ownership. What should I do? I've chosen to not mention the Sets here, unless you all need me to. The Help Form has the information there, along with the Auction record reference. Let me know if I need to provide specific information/details here, or if I need to go about this using a different format other than the NGC Set Registry Forum. Thanks in advance, Poobah
