A 10-dollar bill that is worth half a million dollars.</s>RENEE MONTAGNE, HOST: Billy Baeder is a currency collector whose first word of advice about a new bill is don't fold it. His second word, check the serial number.

He has a 10-dollar bill known as 1933 silver certificate, one of a small batch of bills the government released and then tried to removed from circulation.</s>RENEE MONTAGNE, HOST: His bill contains a unique serial number, the letter A, then seven zeros followed by one A. That means it was the first off the printer, making it even more rare and worth $500,000.</s>STEVE INSKEEP, HOST: Zero, zero, zero, zero, zero, zero, zero, one, A. But Mr. Baeder is not willing to part with his Hamilton for any number of Benjamin Franklins. He says the bill was bought by his late father, the man who taught him all about the currency trade. It apparently has sentimental value worth more than half a million dollars to him.</s>STEVE INSKEEP, HOST: And that's the business news on Morning Edition from NPR News.
