Some currency factoids:<p>1) North Korea has nearly perfect USD$100 printing plates, and finances imports with them. There have been several news articles written about this.<p>2) In Indonesia, the USD is a parallel currency that individuals/business owners use as a hedge against instability. Typically they'll have a hardbound book with mint USD$100 bills between alternating pages.<p>By mint I mean no holes, no wear, no ink stamps, post 2000.<p>3) I met somebody who had saved $15,000.00 in Indonesian Rupiah towards UK accounting school. Sadly, the month before, the Rupiah was devalued by 90% and he was left with only $1,500. See #2.<p>Typically when you exchange USD$2,000.00 there, you get a brown lunch bag full of Rupiah note bundles. You almost need a duffel bag to do a large exchange or withdrawal.<p>4) The lowest amount, the 100 Rupiah note, worth less than 1 cent, has an orangutan on it. Coincidentally, the strongman Suharto was on the old 50,000 note, worth about $3, the highest amount at the time. Guess which one is called the monkey note? :)
