I guess, but it's quite common for something like that to be done. It shows that they still have respect for their head of state, and that's not a bad thing.
Never said it was a bad thing, but usually they put the faces of people who've actually
done something on money. So far, all William and Kate have done is get born into a royal family and marry some chick who you
only started liking after you saw her half nvde (during a modeling gig), or having rich parents and getting hitched to royalty respectively. No disrespect to them, but they're not
that special.
