Well I finally relented and ordered 10 "true premium" uncleaned coins to give her and I something to do together this summer. The coins arrived today and I am cautiously optimistic about that we will have some decent luck cleaning them. Obviously they are nothing but common LRBs, but I think the discovery of what is underneath will be fun for her. Obviously, sharing your hobby with your kids is even better I plan to post updates as we clean and identify them. Here they are now in all their cruddy glory. 10 were ordered but we actually received 12 which was a nice surprise.
