No data that day.
Dimmed prices have no recorded sale behind them — they are a single reference mark, not a traded figure. Sold data covers graded cards only.
A dash means we hold prices for that grade and refused them: they contradict each other, and which one is wrong is not knowable from the data. A confident wrong price is worse than none.
