Sweden 20 KR gold set impossible to complete?
I have had fun building a nice Sweden 20 Kronor gold set. The only registered public set at PCGS. I am missing one coin for the set and am not sure it I'll ever be able to fill this slot. The registry includes a 1876/5 ST slot. I have never seen one nor can I find any that have ever been graded or sold.
PCGS's population is 0, NGC which has graded thousands more than PCGS has 0, ANACS has 0. NGC doesn't have the slot in their registry set. I have emailed the set registry email address at least 2 times over the past few months and can't even get a reply.
What am I to do? Just live with a slot that can never be filled? Any idea how to get PCGS to remove this slot? It's super frustrating.
