1815 Capped Bust Quarter not being picked up in my registry set
I have a First Year Type Set registry here: https://pcgs.com/setregistry/type-sets/complete-type-sets/first-year-issue-type-set-1793-1964/publishedset/227423
And I have an 1815 Capped Bust Quarter in my inventory here: https://pcgs.com/setregistry/mysetregistry/mycoinfacts/4061432
But for some reason, it's not being picked up in the registry set. Am I missing something? Is there someone I can email about it?
