old british coin?

I have this old British coin that came from an uncle's coin collection I inherited.  I'd like to know more about it. Thanks

Hello. This is the coin.  ½ Sovereign - George V - United Kingdom – Numista  I don't know what's going on the top of the reverse but there's enough wear that with the high gold price it's worth probably just melt value.  Still, a very nice coin.
