In my April journal entry I mulled my options about what step to take in my numismatic quest. I had completed my Morgan Dollar registry set and, knowing I could never climb much higher in the ranks, was undecided in whether to upgrade or move on to another goal. I decided to work on upgrading those coins that wouldn't rush me to the Poor House. I've managed to slide a few coins up a grade or two. However, I've hit a snag. I recently purchased a nice 1885 NGC MS66 to replace a very nice PCGS MS64. Upon trying to register this coin, I found that NGC would not recognize the certification number. The seller had this and other Morgans certified on the same invoice and those others checked out fine when checked through certification verification. I've contacted NGC and the seller and have not received any replies as of yet. Has anyone else out there run into this problem and how has it been resolved? Attached is the info retrieved from NGC and a photo of the slab.
