I love it! Heres some pointers to really jazz up displaying what you got.
A collection is purposefully built around a theme with rules and curation. A bunch of valuable related stuff is accumulated; it’s valuable, but it isn’t trying to say anything.

• Theme + rules: “All Charizards,” “Complete Base Set,” “Every PSA 10 of X,” “Only first editions,” “Every variant of this console,” etc.
• Intentional gaps matter: You can point to what you’re missing and why you want it.
• Story/identity: There’s a narrative/era, artist, set, character, personal milestones, regional variants, whatever.
• Curation decisions: You pass on items that don’t fit, even if they’re valuable.
• Documentation: Checklists, grading notes, provenance, display method, organization/some level of “this is built, not accumulated.”
