Overprints are considered to be major errors. Depending on the nature of your overprint, it could retail in the $150 to $300 range. You should get a couple of competing appraisals from dealers in error currency.
The last $2 red-seal silver certificates were printed in 1896. Nearly all red-seal $2 bills printed after that date are United States Notes, as indicated by the banner across the top of the bill's front. Please look for questions in the form "What is the value of a (date) US 2 dollar bill?" for more details.
This sounds like an offset error and is quite valuable - maybe in the range of $200+. You need to get appraisals from a couple of dealers who specialize in error currency. An offset error happens when a sheet of paper gets stuck and doesn't go through the printing press. Ink is transferred to the opposite side of the press instead of the paper. When the next sheet gets unstuck and goes through, it picks up not just the ink it's supposed to have, but the reversed image from the opposite side of the press.
The Front
Please check the banner across the top of the bill's front. It shows that your bill is a United States Note, not a silver certificate. The last $2 SC's were printed at the end of the 19th century. There's more information at the Related Question.

The $500 bills that were produced from 1928 - 1934 have Presesident William McKinley on the front and just a 500 printed on the reverse.
Back to front printing is a setting that allows your pages to be printed in reverse order, making it easier to staple.
The year should be printed on the front of the bill
Ben Franklin is on the front of the one-hundered dollar bill and Independence hall is on the reverse side.
The U.S. never printed any $1 bills with that date.
This is not possible because the obverse and reverse die strike the coin simultaneously.
U.S. currency is printed in a 3-step process :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.So you can see it's virtually impossible for a partialback side to be printed on the front side.I suggest you take it to a coin show and have a few currency dealers look at it to figure out what you have.
This is great rivi stuff because few people can even tell you who is on the $50 dollar bill. Anyway, the $5000 bill was printed from 1928 through 1934. On the front is President James Madison; on the reverse is just 5000 written between The United States of America and Five Thousand Dollars.
It will have the words Silver Certificate printed across the top of the bill's front. In most but not all cases, the seal and serial numbers will be printed in blue ink.
Foldover errors are very collectible, and retail at upwards of $300.
Decimal currency was introduced in Australia on the 14th of February, 1966. The One Dollar note was predominantly brown and orange in colour, had Queen Elizabeth II and the Australian Coat of Arms on the front, and Aboriginal artwork on the back. All paper money introduced a metallic strip imbedded in the paper to make counterfeiting more difficult. It was a similar size and colour to the 10 Shilling note, which it replaced. There were only two major variants of the One Dollar note - Notes printed from 1966-1972 will have "COMMONWEALTH OF AUSTRALIA" printed at the top, front and back. Notes printed from 1972-1982 will have only "AUSTRALIA" printed at the top, front and back. The Australian One Dollar note was replaced with a coin, first issued in 1984 to replace its paper predecessor.
$2 to $4500 depending upon the mint mark, variety and the condition of the coin.
