Piratehat?

full 256 - around 60k to 75k, its pretty hard to estimate since it's not that popular. Depends on the seller and buyer I guess.

512 - I'm not sure if you mean full 512 as in body and joints, or just joints since you worded that in a weird way, but
full 512 body - 190k to 220k
full 512 joints - 380k - 400k
both - around 500k to 600k
