How does that $16,000 price compare? Well, our Machinery Pete auction sale price data shows the Avg. Auction Price on the last (40) IHC 1206's sold = $12,624. Five years ago (2012) the Avg. Auction Price was $12,278. Incredibly, 15 years ago (2002) the Avg. Auction Price on IHC 1206's was only $4,425.
