Please post a more specific question.
There are NO US Liberty Head dollars dated 1846 but there are Seated Liberty dollars dated 1846. Consult a qualified coin dealer
The New Orleans Mint did not strike any dollar coins in 1848 only in 1846 for that decade.
The 1846 Liberty Seated Dollar has retail values in the circulated grades that run from $216.00 in G-4 to $1,590.00 in AU-58. I suggest having a dealer or collector evaluate the coin for a accurate value.
1846 was the first year for an "O" mintmark on a dollar coin. Look at the coin again and post new question.

The coin needs to be seen for a accurate assessment of value. With a date of 1846 it's one of the "Liberty Seated" series of silver dollars. A coin in average circulated condition has retail values of $250.00-$500.00 or more depending on the grade of the coin.
No, no dollar coins were minted there in 1847. Early silver dollar production at New Orleans was intermittent. They were only struck there in 1846, 1850, 1859, and 1860 before the Mint was captured by the Confederacy. Following the Civil War dollar production at New Orleans was much more frequent.
Retail values for average circulated coins in G-4 to EF-40 are $270.00-$840.00
Please check your bill again and post a new, separate question that might help to ID it. The only federally-issued $1000 silver certificates were dated 1878 and 1891.
There's no such thing.
The mintmark on a Seated Liberty Dollar would be located on the back of the coin, beneath the eagle's talons. It could be "S" (for San Francisco), "O" (for New Orleans), "CC" (for Carson City), or there could be no mintmark, signifying that the coin was minted in Philadelphia. 1846 dollars were only minted in Philadelphia and New Orleans. The San Francisco and Carson City mints weren't established yet. As of 03/2009 Numismedia lists retail prices for an 1846 Philadelphia dollar ranging from $215 for a very worn coin to over $2000 for an uncirculated specimen. If it has an O mint mark the range is $270 to $6000+ In any case you should have your coin professionally appraised.
Unfortunately there's not a specific single identifier for a counterfeit Seated Liberty Dollar a couple of things most people can do is you can weigh the coin it should be 26.73 grams with a diameter of 38.1mm. But this does not guarantee it's authentic. I suggest submitting it to a third-party grading service
