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.
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.
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.

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.

The value of a Saint Christopher protect us medal can vary depending on factors such as the material it is made from, its age, and any ornate details. It can range from a few dollars for a basic medal to hundreds of dollars for a rare or antique piece. It is recommended to consult with a reputable appraiser or browse similar items online to get an accurate estimation of its worth.
On Kennedy half dollars struck in 1964, the mintmark (if any) is on the reverse by the Eagle's left talon. On Kennedy half dollars struck after 1964, the mintmark (if any) is on the obverse right above the space between the second and third digit in the date. On Franklin half dollars, the mintmark (if any) is on the reverse above the bell but below the "E" in "States". For the Walking Liberty half dollar dated 1916 (and some 1917 pieces) the mintmark (if any) is found on the the obverse under the "R" in "TRUST". For later dates of Walking Liberty halves, the mintmark (if any) is found on the reverse on the extreme left hand side under the branch of the perch that the eagle is standing on.
Trade dollars were only minted from 1873 to 1885, and no dollar coins of any kind were minted for circulation from 1804 to 1835. Trade dollars are among the most widely counterfeited dollar-sized coins so if your coin purports to be a trade dollar dated 1817 it's a fake.
No authentic CSA half dollars bear the shield on the reverse and obverse of the coin.
The U.S. Mint did not issue any Trade Dollars or any other dollar coins dated 1930. Please post new question with a complete description of the coin.
Nothing. There is no monetary reward with Olympic medals. Any such financial gain is from commercial enterprises and promotions.
