last swap meet I saw a set on sale for $250.00, they sat the entire day, no one bought em. I saw others on sale early that didnt last all day ranging between $50.00 & $150.00. So, my best guess would be somewhere in the neighborhood of $100.00 for a set of 4. Though if they look real good you can prolly get more for them. I know the local classic parts place sells the metal center caps for $80.00 a set (all 4). But you can buy plastic ones for $60.00 a set from hubcap annies and the look much nicer, even if they are made of plastic.
