US Banknotes

Assuming you're referring to a bill printed after 1928, there are very few fakes because the bill's value is too low to make counterfeiting it worthwhile.

Neither $1 nor $2 bills incorporate modern security features like watermarks or color strips, though. If you're really uncertain about a particular bill, about all you can do is:

(1) Look at the paper to see if it contains tiny blue and red threads. These are added to the paper and are very difficult to replicate in a fake.

(2) Examine Jefferson's image. It should be sharp and the lines should be crisp and regular.

(3) Check the "teeth" in the seal or seals on the bill's front. They also should be sharp and evenly-spaced.

A star next to the serial number on any US bill means that the original note with that number was damaged in printing, and the star note is the replacement.

about 500

All 1928-series US $2 bills were printed as United States Notes which had red seals rather than yellow seals. It's possible that your bill's color has been affected by age or exposure to chemicals.

If your 1928 G bill were undamaged its approximate retail value as of 01/2015 would be about 5 to 10 dollars in average circulated condition, and $25 if uncirculated. However if the bill has been damaged its value would be correspondingly less.

As of 01/2015, HAWAII-overprint bills retail for $10 to $40 in circulated condition. A nice uncirculated one can sell for $135 or more.

Despite the word HAWAII and a 1935 date, these bills were actually printed in Washington DC during WWII. The government was afraid that if the Japanese invaded the islands, any currency they stole could used to destabilize the US economy. The Treasury's solution was to replace standard $1, $5, $10, and $20 bills in that territory with special versions that had brown seals and HAWAII overprinted on both sides. If Hawaii had been captured its special currency could be declared worthless without affecting bills used on the mainland.

The back of the U.S. $2 bill features John Trumbull's painting "The Declaration of Independence." The man wearing the hat is Stephen Hopkins of Rhode Island.

Yes, it means that the bill is a "replacement note" printed to replace a bill that was damaged during the printing process before it was delivered to the Federal Reserve system.

Wild online conspiracy theories notwithstanding, there is no way to track any US bill.

$1,300

All old U.S. currency is still legal tender at face value.

The most recent update was 2013-2014, when additional colors and security features were added including a holographic stripe. Its release dates stretch across 2 years because of printing problems that required the first run of bills to be destroyed.

Two dollars.

Serial numbers are counters and a security feature but rarely affect a bill's value. Some collectors will pay extra for numbers with a special pattern, e.g. 12345678, or very low numbers such as 00000015.

All US banknotes weigh 1 gram each. A US pound is 453.6 grams, so assuming no one is going to tear up 6/10 of a $20 bill, one pound would contain 453 bills worth $20 x 453 = $9060

It's the Treasury Department seal and is a mark of authenticity because it indicates the bill is issued by the US Treasury.

You need to be clearer on exactly what you're describing. The US did at one time print a $100000 bill, but it was never in circulation and it was used basically for internal bookkeeping by the US government (to transfer large amounts of money between departments). Also, it wasn't "gold", but orange.

It's more likely that you've got some kind of (essentially worthless) novelty item.

There is no official 1 million dollar note ever produced by the Bureau of Engraving and Printing (BEP). You have a novelty item that sells for a couple of dollars in gift shops.

Could you check that date? $2 bills were not issued in 1923. For a range of dates and values, try:

Unless it's a small bag, yes.

On modern U.S. bills of $5 or larger, the district is indicated by the second letter in the serial number. The first letter indicates the series.

Silver certificates are a form of representative money used in place of actual physical silver, you can buy them on ebay.
