These are junior preferred shares with a redemption value of $100,000 instead of the usual $25 or $50.
Nothing special about them except they are worth 4 thousand times as much and typically trade for 4 thousand times as much.
These are extremely lightly traded - I think about 30 shares since last summer. So if someone enters a "market" order - and nobody has any up for sale - the price will plummet. In this case down to $1000.
Feel sorry for the person who sold that share, but congrats to the buyer!
