It depends on what date it is, post new question
Based on 2010 values a US 1947 Walking Liberty Half Dollar in regular circulated condition would be worth $7-9 for either mint. This coin in Extra Fine condition $10, About Uncirculated $25, Uncirculated $45-60
It's a presidential dollar, minted in 2010, and it's worth one dollar.
Most halves from the WWII era are common among collectors. Anything that shows evidence of wear will mostly be worth its silver value, around $7-8 as of 03/2010.
The gold is plating that was added later by a private company. It destroys any collector value the coin had, but as of 01/2010 it's still worth about $7-8 for its silver content.
One dollar.
One dollar.
Typically those types of coins are generally worth market value of gold. The 50 dollar coin is 1 troy ounce of gold, so therefore around $1400 as of late December of 2010.
about a dollar because it is a dollar
Without knowing what to compare it against, it was worth one dollar.
It's gold plated, but not gold. The good news is that 1942 is a common date for Walking Liberty halves so you can still sell it for its melt value of $5-7 as of 07/2010. In any case, a gold half dollar would have been about the diameter of a pencil eraser, and no gold coins were made for circulation after the US went off the gold standard in 1933.
A 2010 U.S. nickel is worth exactly five cents.
What you presumably have is a James Buchanan presidential dollar coin. It was minted in 2010 and is worth one dollar.
