Swap meet Saturday I saw two sets.
One were priced too high at $50. Rough on the side that shows and lots of rust on the other.
The other were probably priced fairly at $100 with very little corrosion inside, some minor diings, and some missing paint. I almost bought them, but I'm no where near needing them, so I passed them up.
And for those paying attention, yes I do plan to put Art Deco hub caps on my Advance Design truck.
