If you are looking for an answer with any degree of accuracy then I would recommend including images with more detail and provide the weight and diameter of your coin - good luck.

Definitely this; your photos are terrible to say the least. At least now you have provided it's dimensions.
I can see the date, 1900, and if it's 20mm then it's a half sovereign, relatively rare/valuable if it's from an Australian mint (beware of fakes!): https://en.numista.com/catalogue/pieces24200.html
If there is no mintmark (located beneath the hind legs of the horse), then it is the British issue, worth at least (possibly a bit more than) bullion value: https://en.numista.com/catalogue/pieces13219.html
