I am conscious of what i buy. My premium series are the 100g 4 layer celing coins, the wolpertinger and friends, the coin invest trust evolution of life and skull coins, all of them are antique finish and very low mintage with very unique designs, the Britannia and Rwanda lunar should be a safe bet if the design is a winner and take a gamble on 1 or 2 items a year that really stand out such as the krugerrand, and thank you for the heads up on that one, its doing very nicely.
