Just received my order from Jack & Jill's Kiloware last Saturday. Haven't gone through it all yet but here's review.
"2LBS of Treasure" - Basically 1/2lb of Machins and X-Mas issues from GB and then you get the pick the rest. The 1/2lb of GB is pretty boring, lots of duplication of low values and about 2/4 Machins and 1/4 X-Mas/Other at least in my case. For the rest of my 2lb I picked 1oz of Scandinavia which was reasonably nice, a handful of cat. $1+ stamps; World Mission #2 & #1 which were pretty indistinguishable from me, a pretty global lot except for Asia which was not well represented; and 1oz World Mission Off Paper which seemed to have most of the older stamps in the lot and included a bit of 19th century and some common mint stamps/
I also ordered 1oz of USA Commemoratives - All of mine were common, maybe 15-20 were not soakable -- overall what I would expect for $4.
1oz Germany Semi-Postals - Probably my favorite envelope out of the bunch. Not sure if they have any real market value but catalog value is certainly $100+ for $12 which I was very happy with. My only complaint was that there was a little too much duplication.
1oz Sweden - Mostly small self-adhesive issues from 1990-present. A few from the 60s-70s but overall nothing that interesting, mostly commons.
Here is some of the bounty from the German Semi-Postal lot which I plan on ordering again soon to fill some holes. My favorites are probably the trains, with the cars and butterflies a distant second. As a warning, and I feel like I should have known this before, but I would not soak stamps with holograms as when they curl the holograms tend to crack due to the plastic or metal being inelastic.
