Another fantastic post Stackin'!😆👍
You have a lot of great ideas for grabbing the boys attention!
I just bought my youngest boy (9) the new star wars and star trek foil notes from the NZ mint, (got them in the mail yesterday) he loves collecting his coins and banknotes so it's a nice fit for him. He understands that silver is precious!
keep it up my friend, you've just got to grab their imagination to foster the stacker in them!😂💕
