Value of three coins dated 1853, 1872 and 1927 ?

A friend has asked me to give him a rough value of a 1927 silver Chinese coin, a 1872 gold sovereign and a 1853 dollar coin, which i think is gold ? I am only into modern coins so i absolutely have no idea on condition / value of older coins. Had a look on Ebay and obviously the prices very quite a lot. Anyone have any estimates based on the photos ?

I cannot comment on value but you may want to test the Chinese coin as there are a lot of fakes.

Now had a chance to research these coins, i estimate the sov £250 - 300, the dollar £100 - £200 and the China silver £50 - £150 ( if genuine). Good quality graded versions going for higher prices.
