The Turks Caicos Islands 50 Crowns Winston Churchill Centenary coin is not worth any more than its gold bullion value (there is no real collector premium). Since it contains 0.1447 oz gold, and since gold is currently trading at (approx) $903 per oz, that would make its current value about $131.
The 1965 'Churchill' Crown was mass produced in 1965. 19,640,000 were struck in cupro-nickel (an alloy of copper and nickel). They are worth today (September 2010) between 50p and £1 depending on condition.
This is a 1 ounce gold bullion coin. The value is tied to the spot price of gold at the time of sale. Now it's $1,236.30 per ounce, this is the approximated value of the coin.
The value is 1/10th of a ounce of gold which as I type this is $1,124.70 per ounce. So the value of the coin is about $112.47. Actual cash value will be different at time of sale
The spot price of gold is $1,115.40 per ounce as I type this, that's also the value of the coin. The coin is 1 ounce of pure gold.
Try eBay or a reputable coin dealer. They do not have all that much value , so do not go to too much trouble. British 1965 Crown - Churchill commemorative.
