The token is hidden at roughly (52.073739, -1.026107). This is by/at Silverstone Circuit. There is a sign for a horse crossing and near by a post with a 40 speed limit sign and on the other side a no stopping sign. The token was hidden one one of the 3 signs or hidden in the stone structure between the signs.
I think the token was hidden on the river wall at the pointy end (North) of Three Mills Island, London. The approx. lat/long is 51.530107, -0.006847. I'd search along the edge of the wall a metre or two each side of the above lat/long.
Thought I might as well submit this as well. Greenwich Park, near the coffee kabin. Correct location for the Meridian. 51.4775, 0.0000. Token would need to be buried I expect. Or... above the front door of the Plume of Feathers pub, 49 Park Vista, Greenwich
