All British Halfcrown coins, up to but not including 1920, were made from sterling silver (92.5% silver).
No. There were no Proof Halfcrown coins minted from 1840 to 1849 inclusive.
Sorry no US 1845 silver eagles, but there are Seated Liberty dollars of 1845.
Silver carp was created in 1845.
A British 1850 Halfcrown, uncirculated and in absolute mint condition could fetch up to £1,100 GBP. If it has been circulated but still in good condition, it might fetch up to £40 to £550 GBP. A British 1850 Halfcrown (Proof FDC) is considered extremely rare. A reputable coin dealer will be able to give a more accurate valuation.
26.73 grams, 90% silver

James Hughes - British politician - died in 1845.
Such a coin does not exist. The first British Florin was introduced into circulation in 1849.
No. It would be composed of Silver (90%) and Copper (10%), and so would not be attracted to a magnet.
Look at the coin again all 1845 Liberty Seated dollars were struck in Philadelphia, so an 1845 can't have a CC mintmark,and the Carson City Mint did not exist in 1845.
James Leith - British Army officer - died in 1845.
Well its about 100-200$ if it is in good condition.
