Help with Commemorative Panes with FDCs

[ChloeeeTattoos]

Hi everyone,

I'm brand new to stamp collecting and recently inherited a small collection. Among the items are several USPS commemorative panes that are still sealed in their original USPS plastic sleeves, with what appear to be First Day Cover (FDC) envelopes included in the same packaging.

Some panes have the First Day of Issue marks on the actual stamps, while others don’t but do still include the FDC envelopes.

I’m trying to figure out the best way to catalog or list these items, but I’m unsure how these kinds of sets are classified. Are they considered:

A regular pane plus a separate FDC?

A special USPS-issued set with a unique catalog entry?

Or something else entirely?

I'm hesitant to open the packaging since they're untouched. Would it be better to keep these sealed for value, or should I open them to catalog the FDCs and panes separately?

Any help would be appreciated, including any pointers on how to find these in Colnect's database or whether there's a special category for this type of USPS release.

Thanks in advance for your guidance!

These look like they are still in the original packaging used by the USPS philatelic center to ship out items ordered back in that era. They are not a separate collectible in themselves, they appear just never have to been taken out of the packaging they were shipped in.

Depending on how you wish to display them if you want to keep them, you could open them up to separate the panes from the First Day covers. Of if you just want to sell them, keep them in their packaging so that if you sell the item you have them already packed up and ready to ship.

@DJCMH Thank you so much for the guidance. Your explanation really helped clarify things for me, and I appreciate you taking the time to respond. I’m still learning, but this answer gave me a much better understanding of what I have/what to do from here!
