This is such a good idea, I’m going to use it for my kids.

I feel sorta bad that it’s hard for kids to collect interesting coins these days (at least here in Canada). When I was a kid in the 90s I could go through the till in my parents’ store at the end of the day and hunt for all kinds of rare and interesting coins, silver, etc (my folks always let me buy out whatever coins I wanted). In 2003, Canada started alloy recovery (taking first silver and later nickel and copper coins out of circulation because the metallurgical value exceeds the face value) and it kind of took all the fun out of the hobby. I don’t think I’ve seen a silver Canadian coin ‘in the wild’ in the last 10 year. This isn’t a criticism, alloy recovery is obviously the right policy decision. I guess I’m just nostalgic.
