If the coins have "TRADE DOLLAR" on the reverse and ARE dated 1846 & 1848 they are FAKE. The first Trade Dollar was issued in 1873. But some people do mistake Liberty Seated dollars for Trade Dollars. Mostly because of the similar obverse design.
Look at the coin again and post new question.

Yarmouth Nova Scotia Trade Dollars are collectible tokens used as part of a local currency program to encourage spending at participating businesses. While they may have value to collectors or as souvenirs, they are not considered legal tender and cannot be used as currency for general transactions.
Please check again. The U.S. did not make any dollar coins of any kind in 1906. Trade dollars have that phrase on the back and were only issued from 1873 to 1885. Morgan dollars were issued from 1878 to 1904 and again in 1921
Simple answer is NO. Some fakes are made from low grade silver but most are not. So it may have a little value if it is silver.
They're not silver, they're brass. The last silver dollars were made in 1935. In any case Sacajawea dollars are not rare at all, and any that you get in change or from a bank are only worth face value.
Us currency has a stable backing is unlikely to suddenly lose its value and is acceptable to nearly any one that wants to trade.
No. US Trade Dollars were minted from 1873 to 1885. Designed by William Barber, they all carried the same reverse which was a portrayal of the America Eagle.
It is illegal to buy Americans, or any other people, with any currency including Haitian dollars.
At any foreign exchange or bank office.
Any bank.
No. Perhaps you have a Trade Dollar, issued for overseas commerce. If so it'll have the words Trade Dollar on the reverse. As of 06/2008 1878-S trade dollars are worth $80 to $190 depending on condition, and 1878-CC trade dollars are worth $800 to $2000.
The U.S. did not strike any silver dollars with that date. The only dollar-type coins issued that year were Trade Dollars. See http://www.numismedia.com/fmv/prices/trddlr/pricesgd.shtml for a price guide. If your coin does not have the words "Trade Dollar" on the reverse I'm afraid that it is a fantasy piece or possibly an outright counterfeit.
