I'm an avid fan of the American Silver Eagles. I take pride in maintaining a 100% NGC collection. I may not be the highest ranked but I have all of them, varieties included. I'm just wondering where, from April 10, 2017 to April 16, 2016, a mysterious 2016(S) Minted in San Francisco variety was added? I've never seen one listed for sale and there is no population report available. It's second quarter 2017, they didn't just mint them. Where's this mysterious coin? I notice there is now a spot for the 2017(S) Minted in San Francisco variety so I expect it will be issued sometime this year (but, why have a slot for a non-issued coin?) and will be on the look for it. The 2017S PF slot is now available as the coin was released recently and I already have my coin ordered for it. I missed out on the unlimited purchase quantity available from the mint because the big companies bought all of them in 2 minutes. I would welcome a reply from NGC as to how these mysterious slots came from.
