Alignment errors on U.S. currency vary significantly in value. If the image is still all within the borders of the paper it's considered a minor error and is generally worth very little above face value if anything. However, if the printing is far enough off that part of the image of another bill is visible, it's much rarer and could sell for $200 to $600 depending on the extent of misalignment. You would have to take the bill to a couple of dealers who specialize in error currency to get competing estimates.
There have not been any $3 bills printed. Anything that looks like a modern US bill but says "$3" is a novelty item worth only the paper it's printed on.

There is no more 1$ Canadian paper money printed. It's now 1$ coin, 2$ coin, 5 $ paper, 10$ paper, 20$ paper, etc. So a Canadian paper dollar might just be worth MORE than a dollar... Check with favorite local numismatist. Condition of the bill in question is a deciding factor.
You'd need to have your bill inspected in person. Seals can be missing because one phase of the printing process was accidentally missed, or they can be printed on the other side of the note (sometimes harder to see) because the paper sheet on which the bill was printed was improperly fed through the press. Depending on the nature of the error your bill might retail anywhere from $100 to $500.
There were no series of 1951 $100 bills ever printed.
