By the mint mark on the reverse of the coin, but silver dollar coins with no mint mark are made in Philadelphia
ZERO, because no dollar US coins were made dated 1970
There's no such thing as a gold silver dollar. Dollar coins were made of gold (1854-1889) or silver (1794-1935) but the 2 metals were never mixed. Most likely you have a silver dollar coin that was plated. Unfortunately being plated reduces its value to that of the raw metal in it, about $10 as of 06/2009.
Look at the coin again and post new question, no US one dollar silver coins were made in 1809

The original dollar coin was made of Silver. The current dollar coins are made of Copper, Zinc, Manganese, and Nickel by the United States mint. The Morgan Silver Dollar is prized by coin collectors.
Dollar coins made in 1935 and before contain .77344oz of pure silver.

No there was not. No U.S. one dollar coins were made in 1968.
American circulation coins were never made of pure silver. They contained at least 10% copper for hardness. 1971 dollar coins for circulation contained NO silver - they were made of copper and nickel. Collectors' coins were struck in 40% silver.
After the Bank Holding Company Act of 1970 was passed, silver was no longer used in making half-dollar and dollar coins meant for general circulation. Some coins made for collectors may still have silver content.

1794 - 1935.
Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
Depends entirely on WHICH US one dollar coin. In the coins made in recent years, there is none.
