Europe has a 100 Euro note worth over $100 U.S., a 200 Euro note worth over $200 U.S., and a 500 Euro note worth over $500 U.S. So, we in the U.S. should have $200, $500, and $1,000 Federal Reserve notes to counter these large Euro notes. And due to the fact that, a $1,000 bill today, going back to July 14, 1969 when $500, $1,000, $5,000 and $10,000 bills were pulled from circulation, is worth what a $100 bill was worth back then.
Also, with the cost of living going up, and the cost of the government having to print more and more $100 bills, which are steadily growing in demand, $200, $500, and $1,000 bills would save millions of dollars in the long run. Plus, carrting a couple $200, $500, and/or $1,000 bills would be less noticible to muggers, pick-pockets and other thieves
