Closing a first-appearance NFT set without a rumour column
First-appearance hunting in Marvel NFT comics tempts people to add unofficial rows for covers that never dropped. Those ghost rows make a set look incomplete forever.
List only issues the marketplace has already shown. If a later cameo is announced with a date, add it then—not because a forum thread feels confident. A collector checklist should be able to reach 100 percent of published lines.
When a first appearance is a variant of a larger run, keep a cross-note to the issue-run sheet so you do not buy the same edition twice under two headings. That cross-note is ink, not a trading alert.
