WOW! HOW MANY ARE THERE!

I PURCHASED 35 '07 W SILVER EAGLES, AND OUT OF THOSE 35, I RECEIVED 30 NGC MS70 EARLY RELEASES. I MEAN WOW! MY EXPERIENCE WITH NGC HAS DEALT ME SOME VERY NICE GRADES ON MY SUBMISSIONS, BUT 30/35. THAT HAS TO BE A RECORD OF SOME SORT, THAT IS LIKE 89% WAS GRADED A 70. I HOPE THEY KEEP THIS UP, I LOVE HAVING THE 70s IN MY SET, BUT I'M AFRAID OF THE DECLINING VALUES, DUE TO THE QUANTITIES, THERE ARE 5100 MS 70 '07 Ws, OUT OF 25,000 GRADED, THAT SEEM HIGH TO ME, UNLESS THE MINT HANDLES THESE COINS DIFFERENTLY THAN THE REGULAR SILVER EAGLES, WHICH IS POSSIBLE, THEY ARE ENCAPSULATED. BUT, 20% STILL SEEMS TO BE A HIGH RATIO. JUST A THOUGHT. ANY THOUGHTS YOURSELF ABOUT IT?
