A 1927 British Penny looks very similar to all British Pennies minted from 1911 to 1936, other than the date.
See the link below and look for the 1936 Penny towards the bottom.
All British Pennies from 1982 to 2008 look pretty much the same as the Penny shown at the link below.
All British Pennies from 1895 to 1901 are near identical. Pictures of a specific coin are difficult to come by. Frequently you should be able to find one on eBay, but the picture is withdrawn after the coin is sold. See the link below for an image of an 1897 British Penny.
Other than a very few minor differences, the 1914 British Penny is very much the same as all George V Pennies issued from 1911 to 1936. See the 1936 Penny at the link below.
It looks exactly the same as the 2010 or 2012 penny.
The US coin looks very much like a modern US penny
You can, my aunt let me look through her pocket change and I found a 1920, 1927, and 1929 penny!
It is silver

There is no such thing as a 1927 Corvette. LOL, hope you didn't buy one.
Take another look at that date. Given that the year 2017 is still five years away, no real coins will have that year yet.
It looks exactly like the US cent.
One Shilling coins were potentially minted by most of the British Empire/Commonwealth countries having their own currencies based on the British Imperial currency system in 1927. The 1927 Australian Shilling has the Australian Coat of Arms on the reverse. If you look at the teeny tiny printing in the scroll at the bottom of the Coat of Arms, you will see "ADVANCE AUSTRALIA". All Australian coins have "AUSTRALIA" on them somewhere. The 1927 British Shilling shows a lion rampant on a crown on the reverse. British coins are almost unique in the world by never having the country name on them.
