No price for unscrolled copies yet, so this one mixes every copy, scrolled ones included. Median of the newest 10 sales of the last week or so, from a summary of 3 sales seen over about the last week. The middle half of those sales were 1,700 to 2,117. None sold in the last 3 days, so it may be stale. Few sales, so treat this as rough. No player reports in the last 30 days yet.
