So that's massively in QEII's favour. What we don't know, of course, are the world figures, but given today's massive wealth, even the dropping out of India and its billions of coins possibly hasn't even affected QEII's lead.
Looking to the future, i.e. CIII, or whatever he will choose to call himself, I imagine some countries will have ditched the monarch, e.g. Australia at least. Also, IMO, wealth will be more constrained as the world's resources become more expensive to extract and obtain - but if it isn't, and computers reign, then even more money will become electronic.
