In my experience one ender does not mean a whole lot except for the fact you will not wear the Collar which is a good thing. My guess is two silvers in the ender box, though I hope you find a whole lot more. Good Luck.
Gratz on the box, sure beats my week. I only got 17 40% and 2 90%s out of my 4k, again my other 4k didn't come in grrrrrr. On an upside though one of my banks gave me 5 silver quarters they found =)
