No clue.  Nobody has offered to buy it yet.  This is just a test.
Less than half a million is, well.. less than a million so it is less impressive, but perhaps someone would be willing to pay $1.
Therefore someone else would pay $2!  Perhaps someone want's it for $3, because it must be worth something.
I have no idea what, or where to draw the line.  This Million dollar account will set the president and then I will have an answer for you.
