Interesting. I think very large denominations has largely been outphased in most currencies as the banks settle their internal transactions by digital money rather then by armored car transports.

Like this one:

The largest denomination of currency ever printed by the Bureau of Engraving and Printing (BEP) was the $100,000 Series 1934 Gold Certificate featuring the portrait of President Wilson. These notes were printed from December 18, 1934 through January 9, 1935 and were issued by the Treasurer of the United States to Federal Reserve Banks only against an equal amount of gold bullion held by the Treasury Department. The notes were used only for official transactions between Federal Reserve Banks and were not circulated among the general public.^[5]

What makes me sad is SNPs lack of monetary insight.

But the system which today's giants and titans help guarantee could face new scrutiny if Scotland votes for independence next year. The Scottish National Party is proposing that an independent Scotland arranges with the rest of the UK and the Bank of England to continue to be part of the sterling family.

A state should control its currency or the controller wields power over the state. Surely the euro crisis should have made that obvious?
