There were only two British "Britannia" coins minted in 1797, one was the copper Cartwheel Twopence at 41mm in diameter, the other was the copper Cartwheel Penny at 36mm in diameter. They are identical except for the size.

Apart from George III, the only person depicted on British 1797 coins is Britannia, the female personification of Britain. She is usually shown as being seated and holding a trident and shield. In 1797 she is on the reverse of the "Cartwheel" Twopence and the "Cartwheel" Penny.
George I died during 1797 and was succeeded by George II. So, both George I and George II reigned during 1797.
The only George III coins with Britannia on the reverse are the Twopence, Penny, Halfpenny and the Farthing, but none of them had a milled edge. From 1797, the Penny was 36mm in diameter, the Twopence was 41mm in diameter and both coins were made from copper.

Your coin is either a British 1797 "Cartwheel" Twopence 41mm in diameter, or a British 1797 "Cartwheel" Penny 36mm in diameter. If somebody has drilled a hole in it, it might be worth a few Pence. Modified coins have no collector value.
