The 1952 Carver/Washington commemorative half dollar is common. Circulated coins are $15.00-$18.00. Mint State coins are $20.00-$30.00.
Prices range from $8 in Very Fine to $20 in Almost Uncirculated condition. These are normally known as Washington-Carver halves rather than Carver-Washington.
There's no such coin. If you have a Franklin half with a liberty bell on the back it's worth about $6-7 for its silver content. If you have a Washington Carver commemorative half dollar it's worth $8-12.
This is a commemorative coin. In decent condition about $15 to $30
Both are valued from $15 to $12,000 depending upon the mint mark and the condition of the coin.
The only thing made by the U.S. Mint in 1952 George Washington on it is the quarter. You may have been thinking of the Booker T. Washington / George W. Carver Commemorative Half Dollar, but that's not George Washington on the front, and there's no Liberty on the reverse. So I have to believe you have something that was not made at the U.S. Mint. Please provide more information in this question's discussion area, providing as detailed a description of what's on each side as you can.
