Larry - according to Jim Munding's room key book (2003) the Pony Express key had 5 ***** which means is was hard to get - and now 7 years later, I'm sure it's a lot harder. I don't have either the Pony Express or the Hampton Inn key you posted - and it is not in Jim Munding's book (and there's been no room key publication since Jim's book in 2003).
