16000 of the most common date Morgan dollars wont change the market at all. Literally just a drop in the bucket.
I just skimmed things but the only thing that stood out was the 1887 MS67s that came out. That may affect things it was a somewhat tougher coin in 67. I sold one about 4 months ago and looks like it was nice timing for me.
If there's still a lot of high grades in those bags, those definitely would sell higher than a typically circulated Morgan. None that would be thrown in a 25-30 dollar box intentionally.
