Great choices !

And Kudos to getting your son into it at an early age !

I had a humble stack (10 x 1oz Silver , half 2022 Maples, and half Europa rounds .9999), as well as a 1/10oz of a gold 2022 maple , but I gave my two nephews 1 Silver Maple and 2 Europa rounds each for Christmas. They loved it ! Well worth the slight temporary stack reduction hehe ..

Well done bud ! Keep stacking <3
