It's a Lauer Model Half Farthing.
Apparently there are several combinations of reverse and obverse.

That one seems to be a "Reverse 3" and "Obverse G".
Description from the link for that combination is:
"Edward VII, Jubilee Mule (Muled with the 1897 reverse - Edward VII never celebrated a Jubilee), Copper, legend spacers (closely spaced and aligned), small ampersand, six pointed star, decorative font"
Edit: Although not sure why it mentions ampersand, the ampersand is only on the Victoria obverse.

I'm not an expert in any kind of coins, but I reckon I'm good at research and will do my best to help. Feel free to tell me my identifications/valuations/gradings are wrong. It's the only way I'll learn.
