LandLeviathan's 2017 W American Silver Eagle Bullion Coins : Proof

What this coin looks like (obverse, reverse, mint mark location, special features, etc.):


Philadelphia and San Francisco and West Point Mint all produced 2017 bullion silver eagles (without mint mark). The combined mintage figure for all Mints are 18065500. The last known mintage figure in 2017 (while coins were still being produced and numbers will likely increase) for Philadelphia was only 1000000 - making them rarest. San Francisco had a mintage of 3000000 - also making them rarer.

Background: Due to strong demand for bullion Silver Eagles - the US Mint began minting these in San Francisco in 2011 to help supplement production and keep up with demand. People knew about them being minted in San Francisco because the Mint used to provide this information on the packaging. However in 2014 - they removed this information from their packaging. Because bullion silver eagles never have mint marks struck on their coins - it was impossible to determine which mint was producing the coins.

NGC began to notice small differences in the quality of the coins - particularly the West Point coins being of higher quality. West Point silver eagle coins are placed into tubes by robots - while Philadelphia and San Francisco coins are put in tubes manually. NGC also noticed differences in the serial number codes on the 500-coin "monster boxes" that silver eagles are distributed in. Due to a Freedom of Information Act request - the Mint released Mint identification information based on these serial numbers:

West Point - 2014-2017: Contains a 6 digit serial code starting with "1" - "2" or "3" - or a 5-digit code with a WP prefix.

Philadelphia:
2015: Contains 5-digit code staring with "1".
2016-2017: Contains 6 digit code starting with "5".

San Francisco:
2014: Conains red-colored strap on monster box.
2016-2017: Contains 6 digit code starting with "4".
