Practical collecting content — seal types, die materials, handle construction, and what drives value in each sub-category.
Why this page exists
Antique seal content online is split between sphragistics (the academic study of seals in manuscript contexts) and modern rubber stamp craft communities — neither covers the collector's perspective on antique hardware. The key distinctions are die material and engraving quality: a machine-cut rubber stamp and a hand-engraved brass matrix for an armorial seal are both "stamps" but occupy different worlds entirely.
Postal cancellation devices have their own collector community (marcophily) with specialized reference literature; wax seal matrices have an older history as personal and official authentication objects; and notary seals are practical instruments that cross into legal history collecting. All three show up together at estate sales, and knowing which is which matters.
