Jhon E Cash Rare Currency's specialty is buying and selling US $5,000 and $10,000 bills. Over the past 27 years we have been the largest buyer and reseller of $5,000 and $10,000 notes in the US. we personally bought and sold over 198 $5,000 and $10,000 bills. . I have purchased and resold over 68 of the 100 Binion $10,000 bills alone, some of them 3 and 4 times. I also maintain the official census of the $5,000 and $10,000 bills with a lot of data on each one. I have a new book due out in late 2026 on the "History and Census of the US $5,000 and $10,000 bills". I have been working over 20 years on this book and I'm excited to be close to finishing it.
