I think it is a piece of jewlery not coin but cant tell .cant find anything online about it eather. feels soft like it could be real gold but not sure any help with identifying would be greatly appreciated thank you ...
Either a token or a piece of jewelry of some sort. Not a coin. You can see where there was something soldered to it at the top and the right of the crown.
Good luck. Lots of tokens were made around the time of her coronation, which this looks like it may be.
I have one made of brass. It had a loop on top to use as a pendant but that got broken off. I believe these come from the early days of her reign due to use of Regina instead of Queen. Even thou Regina means Queen.
