I'm pretty new to the stacking game. I'm a complete pm junky and want to diversify and add platinum and palladium to my stack. I don't normally have enough $ to buy 1 oz of the stuff at one time so I was thinking about 1/4 oz 1/10 oz or maybe 1/2 oz coins. What are my options. I know there is a 1 oz platinum and there are 1/2oz 1/4 oz and 1 oz palladium maples. Any other cool coins that I should look into and what kind of premium am I looking at. Thanks in advance.
