Recent US Stamp Issues For Trade

I have some leftovers from recent issues for trade...maybe someone needs some before I use for postage.




I have more of the coils (Patriotic Spiral, Nonrprofit USA, 1c Apple)
Some coils have back numbers (do not collect) but I have removed the plate number strip.

I am interested in:
1. clear mounts (55mm) Showgard/Scott- Prinz
2. US plate blocks - prior to 1954 (pre Scott 1030) or post 1979.
3. Liberty blocks - want wet and dry samples
