What a great (dark-side) numismatic gift for kids!
I was browsing the Royal Mint site and clicked on their tooth fairy category. [LOL. YES! They have one.] The have some children's books about the tooth fairy but also this great little coin gift for a lost tooth.
Rather than The Mighty Minters, this is the kind of thing I think the US Mint should create for kids. Inexpensive holiday gifts. Why not an NCLT Halloween series and an Easter Series? Do them in copper-nickel for kids and maybe silver for adults.
