My favorite silver to stack is the silver kind. 😉
I like “travel” silver. So coins and bars that have places on them or are obviously connected to a place. Things like America the Beautiful Art Bars, or the Route 66 shields. There is this icons of Great Britain series where each coin depicts a British landmark. I like Koalas as they are obviously representative of Australia.
Stacking silver is the best silver. I like the idea of travel silver. If only I could get a silver round when I take the kids places like they make rolled pennies! That would be great..
