Check the listing count
Open the card in Movers or its detail panel. A badge like2 LISTED means only that many copies are listed in the card’s condition. With this few for sale, the lowest listing price is a weak signal — one seller’s price effectively sets the whole market. No badge means either a healthy market or no depth data captured yet.
Check for an active buy-out
ABOUGHT OUT · 2H AGO badge means the listings just got cleared and the price is moving right now. This isn’t the same as “thin” — a thin market can sit quietly for weeks, while a buy-out is an active event. Both call for the same caution: don’t take the current number at face value.
