You are right. The old pump 22s just shy of being beat to hell are $300 and the "good" ones seem to be going for $500-$700+.I've seen Winchester 62A's and Remington Model 12's sell in the $300 range, but it's going to be a beater. I'm not sure why, but old pump 22's in good shape seem to be peaking over the last 6 months.
Anything in "collector grade" is going $1000+.
