In completed items they go for from $75 to $300! WOW.
When I was buying them heavily (maybe 5 to 7 years ago) a standard working CC was $25-50.00, a power CC was $250-350. Last time I checked (a couple years ago) they were going for nothing: $5-10.00 + shipping.
Interesting how things change over time.
I fortunately have several working examples and one is a Chinese CC with OS7.1T Japanese, all documentation, even the original purchase receipt. I even found a box for it (not THE original and no original foam packing). I am keeping it for the museum...
with older machines becoming more rare, they go up in price. Especially a coveted machine like the CC and CC2. The mac128k/512k/plus are prime examples of this. I sold a 128k last year for $200. That included no keyboard, mouse, or operating system disk. Also, the image on the screen didn't fill the whole screen. Some dude in Japan bought it. Musta REALLY wanted it...
