Rothhhamer,

Love the gold certificates and the large denomination bills - thanks for the photos.

I believe I once saw either a $500 or $1000 US bill in circulation somewhere but I can't remember the context.

The trouble with collecting these things is the high price of entry (not to mention securing them). There is no discount for a 50% condition $10,000 note and I don't know whether they even exist in that condition unless stuffed away in an attic somewhere. (I saw a news piece about a couple who found metal boxes filled with $120K in 1920's notes in the walls of a house they were remodeling.)

I think it's true that the 100K notes were only ever used for exchanges between Federal Reserve Banks back in the day.
