The classic run collectible. A lathed twenty-sided blank carries a raised rim, a field sunk 0.007 m below it and twenty milling beads round the edge. A six-point mint star, an original abstract mark rather than any real currency device, stands 0.006 m proud of both faces so the coin still reads when it turns edge on. Bounding size 0.38 by 0.38 by 0.06 m; metres, +Y up, +Z forward. Origin: free, at the centre of the coin, on its spin axis, because a collectible like this is hung in mid-air at whatever hover height the level needs and a base origin would put it on the floor. The geometry surrounds the origin, reaching 0.189 m below it and 0.189 m above it. Clips: bob (2.4 s), spin (1.6 s). Rigid node animation only: named nodes with translation, rotation and scale clips, no skinned rig and no skeleton. No collision volumes and no navigation data. Opaque materials throughout; the pack uses no alpha blending and no transmission.
