My daughters silver stack

I started this stack for my daughter about 2 years ago. I had the idea to buy an old looking treasure chest to keep it in. She loves it! Every now and then we take it out and play “treasure”. She’s only 4 but I try to teach her that it’s real money and that it will be worth a lot more hopefully when she’s older. I think it’s a fun investment for kids, they get to physically get to hold it and “play” with it and get to collect new kinds all while slowly building a little wealth! Do yall do this with yall kids?
