US Banknotes

The only bill fitting that description is a silver certificate. Please see the question "What is the value of a 1923 US 1 dollar silver certificate?" for more information.

Please check your bill again and post a new, separate question. There were no federally-issued $10 bills dated 1899.

Please post a new question with the issuing country. The U.S. didn't print any bills dated 1958

$2 bills dated 1976 and later are only worth face value, but older ones can be worth a premium. Their extra value ranges from only a small amount (50 cents) to thousands of dollars depending on their date and series letter, but without more specific information it's not possible to give any idea of an individual bill's value.

There is no such thing as a set value for anything. Something is worth what someone is willing to pay right now. Prices can fluctuate daily.

Ebay is a good place to look for current values. If you have an account you can see the completed auctions and the prices that are being paid. IT IS NOT JUST AN ESTIMATE BUT ACTUAL SALES! That should give you an idea as what yours might bring should you list them on Ebay.

I talk to many dealers who are surprised at the prices people pay on Ebay. The dealers I know will not pay what Ebay sellers are getting.

The state quarter program created millions of new collectors and I think a lot dealers have yet to recognize that fact. More buyers equals more demand which leads to higher prices and a wider range of collectibles. Of course it's the old supply and demand thing.

In coins and paper currency the condition and rarity along with supply and demand determines value.

You will see on Ebay that even new money is bringing a premium.

Despite its age, as of 05/2010 it's only worth face value to $140 in circulated condition regardless of its series letter.

A nice uncirculated one might retail for $175 or more.

Please post a new question with more details. What's the bill's date and seal color? What does the suspected misprint look like?

100 dollars of course!

The U.S. government did not print any $10 bills with that date.

Your bill may have been issued by a private bank, which was common in that time. If so please post a new question with the bank's name.

There were no $1 coins or federally-issued $1 bills dated 1920. Please post a new question with more details.

There are no 1950 $1 bills. The nearest dates are 1935 and 1957.

Please look again and post a new question.

All US paper currency is printed by the Bureau of Engraving and Printing.

Popular misunderstanding to the contrary, the US Mint does NOT make paper money, they only strike coins. The Mint and BEP are separate departments in the government.

The US didn't print any bills dated 1956. Please check again and post a new, separate question.

Please check again and post a new question. The only 1933 silver certificates were $10 bills and these didn't have any series letters.

Any 1933 $10 silver certificate should be evaluated in person by a dealer or appraiser, as these bills are very rare and can sell at retail in excess of $4000.

They are illegal to own.

$100,000 gold certificates were never put into circulation and are extremely rare. There are many replicas and fakes, however.

The last $2 silver certificates were made in the 1890s.

If you have a U.S. Note with a red seal, please post a new question with the bill's exact date and what letter, if any, is below the date.

The US didn't print any $10 bills dated 1920, but at that time over 200 private banks issued paper money under federal charter. Because there are so many varieties it's almost impossible to provide a value estimate online; it would be best to have your bill evaluated in person by an expert in antique currency.

The U.S. didn't print any $20 bills (or any other denominations, for that matter) dated 1936. Please check your bill and post a new, separate question.

The US didn't print any bills dated 1939. Please check again and post a new question.

A 1900 one-hundred dollar bill is only worth about $100. If it is in exceptional condition, it could bring in about $105.

The U.S. has not printed any $20 silver certificates since 1891. What you are describing sounds like a private issue. VERY few of these items ever end up being worth as much as they originally cost - there's usually little or no aftermarket demand for them.

As of 06/2014 approximate prices are:

Circulated: $5 to $12 depending on the bill's condition

Uncirculated: $45

Serial Numbers

A bill's serial number is a counter and a security feature. In most cases it doesn't affect a bill's value or help to identify it. Some collectors specialize in bills with low serial numbers (e.g. 00000005) or unusual patterns (12344321) so these can bring above-average prices.

DISCLAIMER: The values quoted are market averages as of the date shown, but may be different for an individual bill due to variations in quality and other factors. Also the wholesale (buying) price of a bill will be less than the selling (retail) price. A reputable currency dealer will be able to give a more accurate valuation based on an in-person inspection.
