What a great story, Jim! And what a great idea, too!
My currently most sought coins are coins with owls on them. My sweet little 2,5 yr old daughter loves owls! To please her, I try to find anything with owls on it (be it T-Shirts or puppets or coins like the Sweet Lake Cities or the Night Hunter coins or other things - see attached the artwork of a stamp, I carved for her ;o).
