What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
The US Mint celebrated the 30th anniversary of the American Silver Eagle coins in 2016. This proof coin is different than in previous years and the 2016 bullion silver eagle - as it features a lettered edge containing the words "30TH ANNIVERSARY" instead of the standard reeded edge. Depicted below is an example image of the lettered edge on the proof coin. Note how the edge is otherwise smooth without the reeding:
