There's no such thing.
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.
There are NO US Liberty Head dollars dated 1846 but there are Seated Liberty dollars dated 1846. Consult a qualified coin dealer
The value of a 1949 Canadian silver dollar depends on the condition of the coin. Such a coin would fetch between 21 and 27 US dollars at auction.

1846 was the first year for an "O" mintmark on a dollar coin. Look at the coin again and post new question.
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.
What year? Please post a new question with that information to help ID the coin.

No. Canada stopped using silver in their 5 cent piece after 1921, and that coin was much smaller than the nickel.
No it's 90% silver and 10% copper with out the copper the coin would be to soft to use
A silver dollar weighs a little less than an ounce.
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.
