Is there a 500 hundred dollar?

Answer 1

"500 hundred" would be 50,000. There has never been a 50,000 dollar bill. There were a few $10,000 bills printed, and an even smaller number of $100,000 bills, used only for transactions between federal reserve banks. There also was a $500 dollar bill, which may be what you're asking about.

None of these bills are still in circulation. They're still technically legal US currency, but the treasury department has been removing them from circulation for over 40 years now and they're worth considerably more than face value to collectors. The highest denomination of US currency still being printed is the $100 bill, and it's unlikely the treasury will ever authorize the printing of larger denomination bills again (there's no longer any legitimate need for them; large currency transfers are now done electronically, and the only people large denomination bills would really help are drug lords and counterfeiters).
