I have a number of jockey molds from the UK, and also a Huxley Box that came with the Lucky Horseshoe 50p chips that I bought a few years back (address is in Edmonton, London but no other detail of interest on the box or Huxley label). I sold several and kept the second box of 100 chips.

When I first saw a chip with this mold when I started collecting, I labelled it as 'skier mold' - still think it's a better description of the mold
