I have them, they were averaging about $40 each at the time. There's two sets - the Wacky 'patch' set (which reprints classic images), and the 'Food Fight' set. They're called patches because the image is printed on a cloth material and they're thicker than normal cards.
The GPK/Wacky subsets have become more expensive over the last few years, I usually try to jump on them as soon as they appear, they only seem to get more expensive over time.
