Hi, Great coins if their authentic. the first one reminds me of the Hibernia half penny. Used in British colonial America. but they were copper. Not sure what these are though. I would do some research on British coins , minted in the 1700,s... good luck and have fun with it...http://www.coindatabase.com/coin_libras_sort_kings2.php?id=2277
Don't want to hijack the thread, but what was the first year Britain put denominations on coins...and what is this one supposed to be, I agree it is a copy.
I think they are English Shillings. 1st one King George II dated 1747 and the second one (nice condition) King George III dated 1787. They have silver content. Quick check to see if they are authenic would be the magnet test, weight and measurement of the coins. Hopefully someone who collects these coins will chime in.

This is a US forum. If you know they're real, its highly likely you know what they are, or you have some idea what they are. The 1787 looks fake to me, I believe it's supposed to be a silver shilling, compare with this real one. Your 1899 is real. Your shilling, I don't think so, jmho.
The Georgian shillings look OK to me, the George the third coin is not uncommon in that condition. Neither are worth spending money on for grading since the value is modest. All the rest are decent but routine British items. It's odd, but we see very little in the way of copies of British coins. US and Asian copies a-plenty, but I have seen more contemporary forgeries than modern fakes.
The coins in the OP are English shillings, and I don't see anything that looks fake about them (I used to collect these, and just sold my collection of them last month). These are both common coins, especially in these conditions. The one on the left is George II, and I'd grade it VG. It looks attractive. The one on the right is George III (you remember, we fought a couple of wars with him...) It is EF details, cleaned/polished. Many of these have been harshly treated over the years. 1787 is probably the most common date for George III shillings.
