To identify originals and restrikes, we first need clear die differences so that others can examine their coins.
Once that has had time to identify 2 or more dies, and we have rough proportions, we can then look for coins whose provenance goes back to the World's Fair or anytime between 1893 and 1896.
With multiple pieces identified, we then determine if there were 1 or 2 dies in use.
Given the small mintage, this activity should resolve itself in a few weeks or months. Then, any coin from a different die pair should be a restrike.
The TPG's should sponsor this examination since they are the ones who will profit from increased re-grading and attribution fees.
[I can do this from coins and auction records, but I would charge a TPG for my time. it's much better for collectors to do this.]
