Those are some great pieces to start your stack. My plan was always to start by buying low premium, high mintage 1oz coins(maples, britannias, philharmonics etc) to build my stack "weight" up, but once I got into it my eye was distracted by pandas, kukaburras and other great deigns. It's not a cheap hobby, but I'm hoping my stack will increase in value as silver skyrockets(fingers crossed). Well that's my plan and good luck on yours. Happy stacking my friend
