For those interested I called and spoke with NGC today about the Smithsonian Holders. The one I posted above was holdered 21 years ago in 2002 but the reverse of the holder looks like the last series holder of 2016, so I don't know. The rep said it was some sort of a promotion she thinks back then. She said she would look into it farther with a supervisor and email me back. Below is her response. I appreciate her and she was very helpful although not alot of further information is available.
Thank you again for speaking with me today! I was able to visit with my supervisor on this, and she actually recently had someone else ask about it as well! So what we were able to gather is that NGC has had "collaborations" with Smithsonian Museum, which you've likely read about on our website HERE. We are unsure what your coin looks like, but here is a coin that was recently graded by us and was sent to us by an individual collector:

With this said, we can still grade and encapsulate coins using the label shown above, but we would need to have some type of "proof" or documentation that any coins submitted were from the "Smithsonian Collection" (i.e. a COA, a receipt from an auction claiming this information, etc.). That was the most information we were able to find out at this time. If you have any coins that may be eligible for this type of submission, please feel free to reach out to us and we can assist you further.
Please let us know if you have any additional questions. Thank you!
