Doily ...one of the more coveted PCGS generations...nice find! See here (although pics are now gone): https://forums.collectors.com/discu...ions-with-pictures-very-long-updated-10-27-06
There is a thread going on the PCGS forum trying to catalogue all known doily holders. Looks like yours isn't on the list. If you're not a member I suggest becoming one and posting pics on that thread to add this one to the list. Or I can do it for you if that doesn't interest you... https://forums.collectors.com/discussion/967317/the-new-doily-census-2016#latest
