There were only 100 of these (Whitepaper 5-year Anniversary commemorative) issued.  https://bitcointalk.org/index.php?topic=269535.msg3452337#msg3452337   The hallmark used for these has since been ceremoniously filed down.    This may be the first one of this issue offered publicly for sale since 2013 ( http://www.ebay.com/itm/Satoshi-Nakamoto-White-Papers-5th-Anniv-COLLECTIBLE-1-ozT-Silver-BITCOIN-Specie/281191054197 ).
