Yep that just happoned to me as well. I remember awhile black when the coins started showing up with black (garda?) wrapers instead of brown (brinks?) massive amounts of 2001 coins were showing up all uncirc. A few years ago i got a box that was just awash with 68, why cant we get solids of those?
I've been hunting for a while and have seen boxes with a ton of new 1996 and 2001 halves but never got a solid box. I hope you can push through the solid boxes, there's a dream box sitting on the same pallet somewhere waiting for you to find it.
