14" to 15" (Pictures added)

Pictures in my reply below!
I am debating if I go to 15" wheels on my 73 Swinger. I was just wondering how much my old wheels would be worth asking for around here without ripping somebody of.

Right now I have a set (4) of 14x5.5 (I think), large bolt pattern (5x4.5) Magnum 500 style Chrysler wheels on my car. They are complete with brushed chrome rings and the center caps with Pentastar emblaim. The only thing I would do is repaint the black (couple chips from lug wrench) or leave as is for a nice driver.

Like I said, I just like to know a fair asking price for the complete set (no tires).

Thanks for the input.
