Yeah but not all at once.

You dump 25 LBs of Stones on the market all at once and its going to affect the price AND catch the attention of people whose attention you don't want.

Also all this was in the bag carried out by an average sized woman, I suspect its closer to 5 pounds.

Edit: Some one els  has done the math.  Once its all sold  think 7 Figures not 6. https://www.paranetonline.com/index.php/topic,53065.msg2318329.html#msg2318329
