Are old first day covers valuable?

Some are, but many are common. Cachet maker, postmark, issue, signature, condition, scarcity, and demand matter.

Do signatures make first day covers valuable?

Sometimes, but signature value depends on who signed it, authenticity, provenance, condition, and collector demand.

Should I remove first day covers from sleeves?

No. Photograph the cover and sleeve first, especially if there are notes, certificates, or provenance.

Value of old first day covers

First day covers need more than a date check. Value depends on the stamp issue, postmark, cachet, maker, signature, condition, scarcity, and whether the cover is part of a larger collection.

Quick value checklist

Identify issue, cachet, postmark date and location, maker, signature, and whether the cover is unused or addressed.
Check toning, creases, tears, stains, fading, corner bumps, tape, and sleeve condition.
Separate signed covers, medallic covers, better cachets, and complete runs from common commemoratives.
