Cut Sheets? How To Collect/Display?

A collection I bought recently at an estate sale has a number of what I am referring to as "cut sheets" - 1/2 of mint sheets in small denominations. What is the proper term for this - postage?

If really anything beyond postage given their value (I presume face value or less) - how do folks store these in their collections.

Thank you in advance for your reply.

Partial panes.

You can keep them in plastic page protectors
or large Vario pages,

For the issues you showed in the picture, those are plate blocks and not half panes (a 1/2 pane would be 20 stamps for this issue). In the 1970s, many US stamps had multiple plate numbers for various ink colors used. Because of the multiple numbers, the plate block size expanded from the normal corner block of 4 with 1 plate number to the block of 12 as you show with 6 plate numbers. A lot of PB collectors stopped collecting when the PB size got big like those shown because the expense of collecting went up by 2-4X.

Joe - do they have any value beyond what several plate blocks might catalog or face value?

I am not Joe but generally no. Because they were so big, lots of Plate Block collectors stopped collecting them and there almost no demand for them today. Good luck.

I wasn't around then but my impression was that this sort of stamp issue killed off plate blocks as a specialty in general. After the 70s lots of big holdings were liquidated at face value or below, as it became difficult and awkward to store the newest issues.
