Always go to the bottom of the bucket/box if you’re looking through the played-with cars. I found this black “skateboard” with some really nice Speed Machines type wheels...

It had shards of a silver body on it, which were quickly dispatched, and it came home with me. It said Anthracite on the bottom, so I looked it up on the bay:

These things aren’t going for pennies, so I feel lucky for getting a set of these wheels for a quarter!
