There is a guy (Chris Duane) that decided to go all-in with silver when the 2008 bank crisis started. I guess he was very passionated about it (has a lot of videos on Youtube that are most shortly said about as he sais "how to become your highest and best self" and what that means for relationships, skills and wealth). It is very interesting. On his way he designed very nice coins which are transporting his points of views and somehow catch the passion he has about it. He privately minted them and the series is called SBSS (Silver Bullet Silver Shield). I took a picture here from a few of my coins I bought from this series: "Freedom girl, 2oz, proof" and "Debt and Death,1oz, double matted". This are early and for me highly collectible coins of low mintage. They are not for stacking, they are more for collecting:)
BTW I dont like his current ones!
