Four denominations were struck in 1906:
Sorry, but 1 dollar gold coins were not issued in 1906. Only 2.5, 5, 10, and 20 dollar gold coins were made. Check your date.
US or British? Post new question.
If the coin is a modern gold bullion coin it is 1/4oz of pure gold. If it's a pre-1933 coin it has .48375oz of pure gold in it.
Sorry, no US dollar coins dated 1906 were struck.
No 1906 US $2.50 gold coins have any Mintmarks or the statue of Liberty on them, please look at the coin again and post new question.
It's not a US coin. The Mint has never made a $100.00 gold coin.
The US quarter eagle has .12094oz of pure gold
No US dollar coins exist dated 1906. Also the coin can't have a "P" mintmark because the first US coin to use it was the 1942 silver Jefferson nickel. Look at the coin again and post new question.
Unfortunately, the US mint did not product any St Gaudens gold coins in 1906. Production first began in 1907. View the link below to see a list of every year the St Gaudens Gold "Double Eagle" was produced and how much each of those coins are worth based on their condition.
9 denominations of US coins exist dated 1906, which one are you asking about.
The US has never made a gold half dollar.
If you have a US silver dollar with a date of 1906, I'm sorry, you have a counterfeit coin. The US Silver dollar was not minted in 1906. Some of these are actually silver coins, and may have a value for the weight of silver they contain, but they are not collector's coins.
