Coin and Paper Money Collecting/C series Ten Dollar Bill with Upside down flag


Dear Mr Fern,

I recently found your reply to another person's enquiry regarding a C series ten dollar bill with an upside down flag.  I actually have one of these in good condition and would be seriously interested in knowing it's value if possible?  I am also interested in selling it if at all possible?  

I await your response.

Yours sincerely


The note has no real value above face unless it is new and Uncirculated. The flag only "appears" to be flying upside down, and is an optical illusion.

For reference on values, see: or

Bills are printed in sheets of 36 notes and in three phases. The back is printed first and taken to a drying room. Next the front is printed and then allowed to dry. Last, the serial numbers and Treasury shield are printed in an overprint press. They then are cut and put into bundles of 100.

For more information, see:

You may want to check US coins and currency listings on eBay from time to time to see if your note is listed what this type of item may bring.

If you live close to a local shop, they should offer an opinion as to the value and if it is authentic at no charge. Remember, should you choose to sell your note, get at least two estimates from professional coin dealers (PNG). I've listed a link for you to find them in your area. Link:

Dealers normally pay between 50% to 60% of retail for items they want.
